171
172 If TPL enabled on the target, get tpl/u-boot-tpl-dtb.bin or tpl/u-boot-tpl.bin
173 if CONFIG_TPL_OF_CONTROL not enabled)
Simon Glassf874fdc2015-08-30 16:55:43 -0600174
175Writing to the board with USB
176=============================
177
178For USB to work you must get your board into ROM boot mode, either by erasing
179your MMC or (perhaps) holding the recovery button when you boot the board.
180To erase your MMC, you can boot into Linux and type (as root)
181
182 dd if=/dev/zero of=/dev/mmcblk0 bs=1M
183
184Connect your board's OTG port to your computer.
185
186To create a suitable image and write it to the board:
187
Jeffy Chen0510e2b2015-11-27 12:07:18 +0800188 ./firefly-rk3288/tools/mkimage -n rk3288 -T rkimage -d \
Simon Glass1510ffe2015-08-30 16:55:52 -0600189 ./firefly-rk3288/spl/u-boot-spl-dtb.bin out && \
Simon Glassf874fdc2015-08-30 16:55:43 -0600190 cat out | openssl rc4 -K 7c4e0304550509072d2c7b38170d1711 | rkflashtool l
191
192If all goes well you should something like:
193
194 U-Boot SPL 2015.07-rc1-00383-ge345740-dirty (Jun 03 2015 - 10:06:49)
195 Card did not respond to voltage select!
196 spl: mmc init failed with error: -17
197 ### ERROR ### Please RESET the board ###
198
199You will need to reset the board before each time you try. Yes, that's all
200it does so far. If support for the Rockchip USB protocol or DFU were added
201in SPL then we could in principle load U-Boot and boot to a prompt from USB
202as several other platforms do. However it does not seem to be possible to
203use the existing boot ROM code from SPL.
204
205
206Booting from an SD card
207=======================
208
209To write an image that boots from an SD card (assumed to be /dev/sdc):
210
Jeffy Chen0510e2b2015-11-27 12:07:18 +0800211 ./firefly-rk3288/tools/mkimage -n rk3288 -T rksd -d \
Simon Glass1510ffe2015-08-30 16:55:52 -0600212 firefly-rk3288/spl/u-boot-spl-dtb.bin out && \
213 sudo dd if=out of=/dev/sdc seek=64 && \
Kever Yangc121f8a2017-11-02 15:16:35 +0800214 sudo dd if=firefly-rk3288/u-boot-dtb.img of=/dev/sdc seek=16384
Simon Glassf874fdc2015-08-30 16:55:43 -0600215
216This puts the Rockchip header and SPL image first and then places the U-Boot
Goldschmidt Simon4d930572017-11-10 11:38:32 +0000217image at block 16384 (i.e. 8MB from the start of the SD card). This
Simon Glassf874fdc2015-08-30 16:55:43 -0600218corresponds with this setting in U-Boot:
219
Kever Yangc121f8a2017-11-02 15:16:35 +0800220 #define CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR 0x4000
Simon Glassf874fdc2015-08-30 16:55:43 -0600221
222Put this SD (or micro-SD) card into your board and reset it. You should see
223something like:
224
Simon Glass419bf142016-01-21 19:45:25 -0700225 U-Boot 2016.01-rc2-00309-ge5bad3b-dirty (Jan 02 2016 - 23:41:59 -0700)

239
Xu Ziyuan5401eb82016-07-12 19:09:49 +0800240The rockchip bootrom can load and boot an initial spl, then continue to
Heinrich Schuchardtf4359782018-06-03 20:41:29 +0200241load a second-stage bootloader (ie. U-Boot) as soon as the control is returned
242to the bootrom. Both the RK3288 and the RK3036 use this special boot sequence.
243The configuration option enabling this is:
Xu Ziyuan5401eb82016-07-12 19:09:49 +0800244
Heinrich Schuchardtf4359782018-06-03 20:41:29 +0200245 CONFIG_SPL_ROCKCHIP_BACK_TO_BROM=y
Xu Ziyuan5401eb82016-07-12 19:09:49 +0800246
247You can create the image via the following operations:
248
249 ./firefly-rk3288/tools/mkimage -n rk3288 -T rksd -d \
250 firefly-rk3288/spl/u-boot-spl-dtb.bin out && \
251 cat firefly-rk3288/u-boot-dtb.bin >> out && \
252 sudo dd if=out of=/dev/sdc seek=64
253
Simon Glass419bf142016-01-21 19:45:25 -0700254If you have an HDMI cable attached you should see a video console.
255
huang lin86d0a902015-11-17 14:20:31 +0800256For evb_rk3036 board:
Jeffy Chen0510e2b2015-11-27 12:07:18 +0800257 ./evb-rk3036/tools/mkimage -n rk3036 -T rksd -d evb-rk3036/spl/u-boot-spl.bin out && \
huang lin86d0a902015-11-17 14:20:31 +0800258 cat evb-rk3036/u-boot-dtb.bin >> out && \
259 sudo dd if=out of=/dev/sdc seek=64
260
261Note: rk3036 SDMMC and debug uart use the same iomux, so if you boot from SD, the
262 debug uart must be disabled

Jagan Teki387fd4b2017-09-27 23:03:12 +0530265Booting from an SD card on RK3288 with TPL
266==========================================
267
268Since the size of SPL can't be exceeded 0x8000 bytes in RK3288, it is not possible add
269new SPL features like Falcon mode or etc.
270
271So introduce TPL so-that adding new features to SPL is possible because now TPL should
272run minimal with code like DDR, clock etc and rest of new features in SPL.
273
274As of now TPL is added on Vyasa-RK3288 board.
275
276To write an image that boots from an SD card (assumed to be /dev/mmcblk0):
277
278 ./tools/mkimage -n rk3288 -T rksd -d ./tpl/u-boot-tpl.bin out &&
279 cat ./spl/u-boot-spl-dtb.bin >> out &&
280 sudo dd if=out of=/dev/mmcblk0 seek=64 &&
Jagan Teki354a9f82017-11-10 17:18:43 +0530281 sudo dd if=u-boot-dtb.img of=/dev/mmcblk0 seek=16384
Jagan Teki387fd4b2017-09-27 23:03:12 +0530282
Heiko Stübnerfdf967c2017-03-24 00:41:34 +0100283Booting from an SD card on RK3188
284=================================
285
286For rk3188 boards the general storage onto the card stays the same as
287described above, but the image creation needs a bit more care.
288
289The bootrom of rk3188 expects to find a small 1kb loader which returns
290control to the bootrom, after which it will load the real loader, which
Philipp Tomsich16c689c2017-10-10 16:21:15 +0200291can then be up to 29kb in size and does the regular ddr init. This is
292handled by a single image (built as the SPL stage) that tests whether
293it is handled for the first or second time via code executed from the
294boot0-hook.
Heiko Stübnerfdf967c2017-03-24 00:41:34 +0100295
296Additionally the rk3188 requires everything the bootrom loads to be
297rc4-encrypted. Except for the very first stage the bootrom always reads
298and decodes 2kb pages, so files should be sized accordingly.
299

Matwey V. Kornilov971fd482019-06-09 00:27:18 +0300307Booting from an SD card on Pine64 Rock64 (RK3328)
308=================================================
309
310For Rock64 rk3328 board the following three parts are required:
Matwey V. Kornilov3a8b1772019-08-02 10:40:04 +0300311TPL, SPL, and the u-boot image tree blob.
Matwey V. Kornilov971fd482019-06-09 00:27:18 +0300312
313 - Create TPL/SPL image
314
Matwey V. Kornilov3a8b1772019-08-02 10:40:04 +0300315 => tools/mkimage -n rk3328 -T rksd -d tpl/u-boot-tpl.bin idbloader.img
Matwey V. Kornilov971fd482019-06-09 00:27:18 +0300316 => cat spl/u-boot-spl.bin >> idbloader.img
317
318 - Write TPL/SPL image at 64 sector
319
320 => sudo dd if=idbloader.img of=/dev/mmcblk0 seek=64
321
322 - Write u-boot image tree blob at 16384 sector
323

327=================================
328
329To write an image that boots from an SD card (assumed to be /dev/sdc):
330
331Option 1: Package the image with Rockchip miniloader:
332
333 - Create idbloader.img
334
335 => cd /path/to/u-boot
336 => ./tools/mkimage -n rk3399 -T rksd -d /path/to/rkbin/bin/rk33/rk3399_ddr_800MHz_v1.20.bin idbloader.img
337 => cat /path/to/rkbin/bin/rk33/rk3399_miniloader_v1.19.bin >> idbloader.img
338
339 - Write idbloader.img at 64 sector
340
341 => sudo dd if=idbloader.img of=/dev/sdc seek=64
342
343 - Write trust.img at 24576
344
345 => sudo dd if=trust.img of=/dev/sdc seek=24576
346
347 - Write uboot.img at 16384 sector
348
349 => sudo dd if=uboot.img of=/dev/sdc seek=16384
350 => sync
351
352Put this SD (or micro-SD) card into your board and reset it. You should see

Simon Glassf874fdc2015-08-30 16:55:43 -0600545Booting from SPI
546================
547
Simon Glass8fbf9922019-01-21 14:53:36 -0700548To write an image that boots from SPI flash (e.g. for the Haier Chromebook or
549Bob):
Simon Glassf874fdc2015-08-30 16:55:43 -0600550
Simon Glass2ac46482015-12-29 05:22:45 -0700551 ./chromebook_jerry/tools/mkimage -n rk3288 -T rkspi \
552 -d chromebook_jerry/spl/u-boot-spl-dtb.bin spl.bin && \
553 dd if=spl.bin of=spl-out.bin bs=128K conv=sync && \
554 cat spl-out.bin chromebook_jerry/u-boot-dtb.img >out.bin && \
Simon Glassf874fdc2015-08-30 16:55:43 -0600555 dd if=out.bin of=out.bin.pad bs=4M conv=sync
556
557This converts the SPL image to the required SPI format by adding the Rockchip
Simon Glass27f8d372019-01-21 14:53:27 -0700558header and skipping every second 2KB block. Then the U-Boot image is written at
Simon Glassf874fdc2015-08-30 16:55:43 -0600559offset 128KB and the whole image is padded to 4MB which is the SPI flash size.
560The position of U-Boot is controlled with this setting in U-Boot:
561
562 #define CONFIG_SYS_SPI_U_BOOT_OFFS (128 << 10)
563
564If you have a Dediprog em100pro connected then you can write the image with:
565
566 sudo em100 -s -c GD25LQ32 -d out.bin.pad -r
567
568When booting you should see something like:

Simon Glassf874fdc2015-08-30 16:55:43 -0600585Future work
586===========
587
588Immediate priorities are:
589
Simon Glassf874fdc2015-08-30 16:55:43 -0600590- USB host
591- USB device
Simon Glass419bf142016-01-21 19:45:25 -0700592- Run CPU at full speed (code exists but we only see ~60 DMIPS maximum)
Simon Glassf874fdc2015-08-30 16:55:43 -0600593- NAND flash
Simon Glassf874fdc2015-08-30 16:55:43 -0600594- Boot U-Boot proper over USB OTG (at present only SPL works)
595

606
607rkimage
608-------
609
610rkimage.c produces an SPL image suitable for sending directly to the boot ROM
611over USB OTG. This is a very simple format - just the string RK32 (as 4 bytes)
612followed by u-boot-spl-dtb.bin.
613
614The boot ROM loads image to 0xff704000 which is in the internal SRAM. The SRAM
615starts at 0xff700000 and extends to 0xff718000 where we put the stack.
616
617rksd
618----
619
620rksd.c produces an image consisting of 32KB of empty space, a header and
621u-boot-spl-dtb.bin. The header is defined by 'struct header0_info' although
622most of the fields are unused by U-Boot. We just need to specify the
623signature, a flag and the block offset and size of the SPL image.
624
625The header occupies a single block but we pad it out to 4 blocks. The header
626is encoding using RC4 with the key 7c4e0304550509072d2c7b38170d1711. The SPL
627image can be encoded too but we don't do that.
628
629The maximum size of u-boot-spl-dtb.bin which the boot ROM will read is 32KB,
630or 0x40 blocks. This is a severe and annoying limitation. There may be a way
631around this limitation, since there is plenty of SRAM, but at present the
632board refuses to boot if this limit is exceeded.
633
634The image produced is padded up to a block boundary (512 bytes). It should be
635written to the start of an SD card using dd.
636
637Since this image is set to load U-Boot from the SD card at block offset,
638CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR, dd should be used to write
639u-boot-dtb.img to the SD card at that offset. See above for instructions.
640
641rkspi
642-----
643
644rkspi.c produces an image consisting of a header and u-boot-spl-dtb.bin. The
645resulting image is then spread out so that only the first 2KB of each 4KB
646sector is used. The header is the same as with rksd and the maximum size is
647also 32KB (before spreading). The image should be written to the start of
648SPI flash.
649
650See above for instructions on how to write a SPI image.

Simon Glassf874fdc2015-08-30 16:55:43 -0600658
659Device tree and driver model
660----------------------------
661
662Where possible driver model is used to provide a structure to the
663functionality. Device tree is used for configuration. However these have an
664overhead and in SPL with a 32KB size limit some shortcuts have been taken.
665In general all Rockchip drivers should use these features, with SPL-specific
666modifications where required.
667
Jacob Chen615cacc2016-10-08 13:47:42 +0800668GPT partition layout
669----------------------------
670
671Rockchip use a unified GPT partition layout in open source support.
672With this GPT partition layout, uboot can be compatilbe with other components,
673like miniloader, trusted-os, arm-trust-firmware.
674
675There are some documents about partitions in the links below.
