| 112 | |
| 113 | All the STM32MP15x boards supported by U-Boot use the same generic board |
| 114 | stm32mp1 which support all the bootable devices. |
| 115 | |
| 116 | Each board is configured only with the associated device tree. |
| 117 | |
| 118 | Device Tree Selection |
| 119 | --------------------- |
| 120 | |
| 121 | You need to select the appropriate device tree for your board, |
| 122 | the supported device trees for STM32MP15x are: |
| 123 | |
| 124 | + ev1: eval board with pmic stpmic1 (ev1 = mother board + daughter ed1) |
| 125 | |

| 144 | Build Procedure |
| 145 | --------------- |
| 146 | |
| 147 | 1. Install the required tools for U-Boot |
| 148 | |
| 149 | * install package needed in U-Boot makefile |
| 150 | (libssl-dev, swig, libpython-dev...) |
| 151 | |
| 152 | * install ARMv7 toolchain for 32bit Cortex-A (from Linaro, |
| 153 | from SDK for STM32MP15x, or any crosstoolchains from your distribution) |
| 154 | (you can use any gcc cross compiler compatible with U-Boot) |
| 155 | |
| 156 | 2. Set the cross compiler:: |
| 157 | |
| 158 | # export CROSS_COMPILE=/path/to/toolchain/arm-linux-gnueabi- |
| 159 | |
| 160 | 3. Select the output directory (optional):: |
| 161 | |
| 162 | # export KBUILD_OUTPUT=/path/to/output |
| 163 | |
| 164 | for example: use one output directory for each configuration:: |
| 165 | |
| 166 | # export KBUILD_OUTPUT=stm32mp15_trusted |
Patrick Delaunay | 5f6fdcc | 2020-02-25 19:04:14 +0100 | [diff] [blame] | 167 | # export KBUILD_OUTPUT=stm32mp15_basic |
| 168 | |
| 169 | you can build outside of code directory:: |
| 170 | |
| 171 | # export KBUILD_OUTPUT=../build/stm32mp15_trusted |
| 172 | |
| 173 | 4. Configure U-Boot:: |
| 174 | |
| 175 | # make <defconfig_file> |
| 176 | |
| 177 | with <defconfig_file>: |
| 178 | |
| 179 | - For **trusted** boot mode : **stm32mp15_trusted_defconfig** |
Patrick Delaunay | 5f6fdcc | 2020-02-25 19:04:14 +0100 | [diff] [blame] | 180 | - For basic boot mode: stm32mp15_basic_defconfig |
| 181 | |
| 182 | 5. Configure the device-tree and build the U-Boot image:: |
| 183 | |
| 184 | # make DEVICE_TREE=<name> all |
| 185 | |
| 186 | Examples: |
| 187 | |
| 188 | a) trusted boot on ev1:: |
| 189 | |
| 190 | # export KBUILD_OUTPUT=stm32mp15_trusted |
| 191 | # make stm32mp15_trusted_defconfig |
| 192 | # make DEVICE_TREE=stm32mp157c-ev1 all |
| 193 | |
| 194 | b) trusted with OP-TEE boot on dk2:: |
| 195 | |
Patrick Delaunay | 6557aa8 | 2020-03-18 09:22:51 +0100 | [diff] [blame] | 196 | # export KBUILD_OUTPUT=stm32mp15_trusted |
| 197 | # make stm32mp15_trusted_defconfig |
Patrick Delaunay | 5f6fdcc | 2020-02-25 19:04:14 +0100 | [diff] [blame] | 198 | # make DEVICE_TREE=stm32mp157c-dk2 all |
| 199 | |
| 200 | c) basic boot on ev1:: |
| 201 | |
| 202 | # export KBUILD_OUTPUT=stm32mp15_basic |
| 203 | # make stm32mp15_basic_defconfig |
| 204 | # make DEVICE_TREE=stm32mp157c-ev1 all |
| 205 | |
| 206 | d) basic boot on ed1:: |
| 207 | |
| 208 | # export KBUILD_OUTPUT=stm32mp15_basic |
| 209 | # make stm32mp15_basic_defconfig |
| 210 | # make DEVICE_TREE=stm32mp157c-ed1 all |
| 211 | |
| 212 | e) basic boot on dk1:: |
| 213 | |
| 214 | # export KBUILD_OUTPUT=stm32mp15_basic |
| 215 | # make stm32mp15_basic_defconfig |
| 216 | # make DEVICE_TREE=stm32mp157a-dk1 all |
| 217 | |
| 218 | f) basic boot on avenger96:: |
| 219 | |
| 220 | # export KBUILD_OUTPUT=stm32mp15_basic |
| 221 | # make stm32mp15_basic_defconfig |
Marek Vasut | 526c951 | 2020-03-31 19:51:36 +0200 | [diff] [blame] | 222 | # make DEVICE_TREE=stm32mp15xx-dhcor-avenger96 all |
Patrick Delaunay | 5f6fdcc | 2020-02-25 19:04:14 +0100 | [diff] [blame] | 223 | |
| 224 | 6. Output files |
| 225 | |
| 226 | BootRom and TF-A expect binaries with STM32 image header |
| 227 | SPL expects file with U-Boot uImage header |
| 228 | |
| 229 | So in the output directory (selected by KBUILD_OUTPUT), |
| 230 | you can found the needed files: |
| 231 | |
| 232 | - For **Trusted** boot (with or without OP-TEE) |
| 233 | |
| 234 | - FSBL = **tf-a.stm32** (provided by TF-A compilation) |
| 235 | - SSBL = **u-boot.stm32** |
| 236 | |
| 237 | - For Basic boot |
| 238 | |
| 239 | - FSBL = spl/u-boot-spl.stm32 |
| 240 | - SSBL = u-boot.img |
| 241 | |
| 242 | Switch Setting for Boot Mode |
| 243 | ---------------------------- |
| 244 | |
| 245 | You can select the boot mode, on the board with one switch, to select |
| 246 | the boot pin values = BOOT0, BOOT1, BOOT2 |
| 247 | |
| 248 | +-------------+---------+---------+---------+ |
| 249 | |*Boot Mode* | *BOOT2* | *BOOT1* | *BOOT0* | |
| 250 | +=============+=========+=========+=========+ |
| 251 | | Recovery | 0 | 0 | 0 | |
| 252 | +-------------+---------+---------+---------+ |
| 253 | | NOR | 0 | 0 | 1 | |
| 254 | +-------------+---------+---------+---------+ |
| 255 | | eMMC | 0 | 1 | 0 | |
| 256 | +-------------+---------+---------+---------+ |
| 257 | | NAND | 0 | 1 | 1 | |
| 258 | +-------------+---------+---------+---------+ |
| 259 | | Reserved | 1 | 0 | 0 | |
| 260 | +-------------+---------+---------+---------+ |
| 261 | | SD-Card | 1 | 0 | 1 | |

| 265 | | SPI-NAND | 1 | 1 | 1 | |
| 266 | +-------------+---------+---------+---------+ |
| 267 | |
| 268 | - on the **daugther board ed1 = MB1263** with the switch SW1 |
| 269 | - on **Avenger96** with switch S3 (NOR and SPI-NAND are not applicable) |
| 270 | - on board **DK1/DK2** with the switch SW1 = BOOT0, BOOT2 |
| 271 | with only 2 pins available (BOOT1 is forced to 0 and NOR not supported), |
| 272 | the possible value becomes: |
| 273 | |
| 274 | +-------------+---------+---------+ |
| 275 | |*Boot Mode* | *BOOT2* | *BOOT0* | |
| 276 | +=============+=========+=========+ |
| 277 | | Recovery | 0 | 0 | |
| 278 | +-------------+---------+---------+ |
| 279 | | NOR (NA)| 0 | 1 | |
| 280 | +-------------+---------+---------+ |
| 281 | | Reserved | 1 | 0 | |
| 282 | +-------------+---------+---------+ |
| 283 | | SD-Card | 1 | 1 | |
| 284 | +-------------+---------+---------+ |
| 285 | |
| 286 | Recovery is a boot from serial link (UART/USB) and it is used with |
| 287 | STM32CubeProgrammer tool to load executable in RAM and to update the flash |
| 288 | devices available on the board (NOR/NAND/eMMC/SD card). |
| 289 | |
| 290 | The communication between HOST and board is based on |
| 291 | |
| 292 | - for UARTs : the uart protocol used with all MCU STM32 |
| 293 | - for USB : based on USB DFU 1.1 (without the ST extensions used on MCU STM32) |
| 294 | |
| 295 | Prepare an SD card |
| 296 | ------------------ |
| 297 | |
| 298 | The minimal requirements for STMP32MP15x boot up to U-Boot are: |
| 299 | |
| 300 | - GPT partitioning (with gdisk or with sgdisk) |
| 301 | - 2 fsbl partitions, named fsbl1 and fsbl2, size at least 256KiB |
| 302 | - one ssbl partition for U-Boot |
| 303 | |
| 304 | Then the minimal GPT partition is: |
| 305 | |
| 306 | +-------+--------+---------+-------------+ |
| 307 | | *Num* | *Name* | *Size* | *Content* | |
| 308 | +=======+========+=========+=============+ |
| 309 | | 1 | fsbl1 | 256 KiB | TF-A or SPL | |
| 310 | +-------+--------+---------+-------------+ |
| 311 | | 2 | fsbl2 | 256 KiB | TF-A or SPL | |
| 312 | +-------+--------+---------+-------------+ |
| 313 | | 3 | ssbl | enought | U-Boot | |
| 314 | +-------+--------+---------+-------------+ |
| 315 | | 4 | <any> | <any> | Rootfs | |
| 316 | +-------+--------+---------+-------------+ |
| 317 | |
| 318 | Add a 4th partition (Rootfs) marked bootable with a file extlinux.conf |
| 319 | following the Generic Distribution feature (doc/README.distro for use). |
| 320 | |
| 321 | According the used card reader select the correct block device |
| 322 | (for example /dev/sdx or /dev/mmcblk0). |
| 323 | |
| 324 | In the next example, it is /dev/mmcblk0 |
| 325 | |
| 326 | For example: with gpt table with 128 entries |
| 327 | |
| 328 | a) remove previous formatting:: |
| 329 | |
| 330 | # sgdisk -o /dev/<SD card dev> |
| 331 | |
| 332 | b) create minimal image:: |
| 333 | |
| 334 | # sgdisk --resize-table=128 -a 1 \ |
| 335 | -n 1:34:545 -c 1:fsbl1 \ |
| 336 | -n 2:546:1057 -c 2:fsbl2 \ |
| 337 | -n 3:1058:5153 -c 3:ssbl \ |
| 338 | -n 4:5154: -c 4:rootfs \ |
| 339 | -p /dev/<SD card dev> |
| 340 | |
| 341 | With other partition for kernel one partition rootfs for kernel. |
| 342 | |
| 343 | c) copy the FSBL (2 times) and SSBL file on the correct partition. |
| 344 | in this example in partition 1 to 3 |
| 345 | |
| 346 | for basic boot mode : <SD card dev> = /dev/mmcblk0:: |
| 347 | |
| 348 | # dd if=u-boot-spl.stm32 of=/dev/mmcblk0p1 |
| 349 | # dd if=u-boot-spl.stm32 of=/dev/mmcblk0p2 |
| 350 | # dd if=u-boot.img of=/dev/mmcblk0p3 |
| 351 | |
| 352 | for trusted boot mode: :: |
| 353 | |
| 354 | # dd if=tf-a.stm32 of=/dev/mmcblk0p1 |
| 355 | # dd if=tf-a.stm32 of=/dev/mmcblk0p2 |
| 356 | # dd if=u-boot.stm32 of=/dev/mmcblk0p3 |
| 357 | |
| 358 | To boot from SD card, select BootPinMode = 1 0 1 and reset. |
| 359 | |
| 360 | Prepare eMMC |
| 361 | ------------ |
| 362 | |
| 363 | You can use U-Boot to copy binary in eMMC. |
| 364 | |
| 365 | In the next example, you need to boot from SD card and the images |
| 366 | (u-boot-spl.stm32, u-boot.img) are presents on SD card (mmc 0) |
| 367 | in ext4 partition 4 (bootfs). |
| 368 | |
| 369 | To boot from SD card, select BootPinMode = 1 0 1 and reset. |
| 370 | |
| 371 | Then you update the eMMC with the next U-Boot command : |
| 372 | |
| 373 | a) prepare GPT on eMMC, |
| 374 | example with 2 partitions, bootfs and roots:: |
| 375 | |
| 376 | # setenv emmc_part "name=ssbl,size=2MiB;name=bootfs,type=linux,bootable,size=64MiB;name=rootfs,type=linux,size=512" |
| 377 | # gpt write mmc 1 ${emmc_part} |
| 378 | |
| 379 | b) copy SPL on eMMC on firts boot partition |
| 380 | (SPL max size is 256kB, with LBA 512, 0x200):: |
| 381 | |
| 382 | # ext4load mmc 0:4 0xC0000000 u-boot-spl.stm32 |
| 383 | # mmc dev 1 |
| 384 | # mmc partconf 1 1 1 1 |
| 385 | # mmc write ${fileaddr} 0 200 |
| 386 | # mmc partconf 1 1 1 0 |
| 387 | |
| 388 | c) copy U-Boot in first GPT partition of eMMC:: |
| 389 | |
| 390 | # ext4load mmc 0:4 0xC0000000 u-boo t.img |
| 391 | # mmc dev 1 |
| 392 | # part start mmc 1 1 partstart |
| 393 | # mmc write ${fileaddr} ${partstart} ${filesize} |
| 394 | |
| 395 | To boot from eMMC, select BootPinMode = 0 1 0 and reset. |
| 396 | |
| 397 | MAC Address |
| 398 | ----------- |
| 399 | |
| 400 | Please read doc/README.enetaddr for the implementation guidelines for mac id |
| 401 | usage. Basically, environment has precedence over board specific storage. |
| 402 | |
| 403 | For STMicroelectonics board, it is retrieved in STM32MP15x OTP : |

| 459 | .. warning:: This command can't be executed twice on the same board as |
| 460 | OTP are protected. It is already done for the board |
| 461 | provided by STMicroelectronics. |
| 462 | |
| 463 | Coprocessor firmware |
| 464 | -------------------- |
| 465 | |
| 466 | U-Boot can boot the coprocessor before the kernel (coprocessor early boot). |
| 467 | |
| 468 | a) Manuallly by using rproc commands (update the bootcmd) |
| 469 | |
| 470 | Configurations:: |
| 471 | |
| 472 | # env set name_copro "rproc-m4-fw.elf" |
| 473 | # env set dev_copro 0 |
| 474 | # env set loadaddr_copro 0xC1000000 |
| 475 | |
| 476 | Load binary from bootfs partition (number 4) on SD card (mmc 0):: |
| 477 | |
| 478 | # ext4load mmc 0:4 ${loadaddr_copro} ${name_copro} |
| 479 | |
| 480 | => ${filesize} variable is updated with the size of the loaded file. |
| 481 | |
| 482 | Start M4 firmware with remote proc command:: |
| 483 | |
| 484 | # rproc init |
| 485 | # rproc load ${dev_copro} ${loadaddr_copro} ${filesize} |
| 486 | # rproc start ${dev_copro}"00270033 |
| 487 | |
| 488 | b) Automatically by using FIT feature and generic DISTRO bootcmd |
| 489 | |
| 490 | see examples in the board stm32mp1 directory: fit_copro_kernel_dtb.its |
| 491 | |
| 492 | Generate FIT including kernel + device tree + M4 firmware with cfg with M4 boot:: |
| 493 | |
| 494 | $> mkimage -f fit_copro_kernel_dtb.its fit_copro_kernel_dtb.itb |
| 495 | |
| 496 | Then using DISTRO configuration file: see extlinux.conf to select the correct |
| 497 | configuration: |
| 498 | |
| 499 | - stm32mp157c-ev1-m4 |
| 500 | - stm32mp157c-dk2-m4 |
| 501 | |
| 502 | DFU support |
| 503 | ----------- |
| 504 | |
| 505 | The DFU is supported on ST board. |
| 506 | |
| 507 | The env variable dfu_alt_info is automatically build, and all |
| 508 | the memory present on the ST boards are exported. |
| 509 | |
| 510 | The dfu mode is started by the command:: |
| 511 | |
| 512 | STM32MP> dfu 0 |
| 513 | |
| 514 | On EV1 board, booting from SD card, without OP-TEE:: |
