6JH7110 RISC-V SoC
7---------------------
8The JH7110 is 4+1 64-bit RISC-V SoC from StarFive.
9
10The StarFive VisionFive2 development platform is based on JH7110 and capable
11of running Linux.
12
13Mainline support
14----------------
15
16The support for following drivers are already enabled:
17
181. ns16550 UART Driver.
192. StarFive JH7110 clock Driver.
203. StarFive JH7110 reset Driver.
214. Cadence QSPI controller Driver.
225. MMC SPI Driver for MMC/SD support.
23
24Booting from MMC using U-Boot SPL
25---------------------------------
26
27The current U-Boot port is supported in S-mode only and loaded from DRAM.
28
29A prior stage M-mode firmware/bootloader (e.g OpenSBI) is required to
30boot the u-boot.itb in S-mode and provide M-mode runtime services.
31
32Currently, the u-boot.itb is used as a dynamic of the OpenSBI FW_DYNAMIC
33firmware with the latest.
34
35Building
36~~~~~~~~
37
381. Add the RISC-V toolchain to your PATH.
392. Setup ARCH & cross compilation environment variable:
40
41.. code-block:: none
42
43 export CROSS_COMPILE=<riscv64 toolchain prefix>
44
45Before building U-Boot SPL, OpenSBI must be built first. OpenSBI can be
46cloned and built for JH7110 as below:
47
48.. code-block:: console
49
50 git clone https://github.com/riscv/opensbi.git
51 cd opensbi
52 make PLATFORM=generic FW_TEXT_START=0x40000000 FW_OPTIONS=0
53
54More detailed description of steps required to build FW_DYNAMIC firmware
55is beyond the scope of this document. Please refer OpenSBI documenation.
56(Note: OpenSBI git repo is at https://github.com/riscv/opensbi.git)
57
58Now build the U-Boot SPL and U-Boot proper
59
60.. code-block:: console
61
62 cd <U-Boot-dir>
63 make starfive_visionfive2_13b_defconfig
64 make OPENSBI=$(opensbi_dir)/opensbi/build/platform/generic/firmware/fw_dynamic.bin
65
66This will generate spl/u-boot-spl.bin and FIT image (u-boot.itb)
67
68u-boot-spl.bin cannot be used directly on StarFive VisionFive2,we need
69to convert the u-boot-spl.bin to u-boot-spl.bin.normal.out with
70the below command:
71
72 ./spl_tool -c -f $(Uboot_PATH)/spl/u-boot-spl.bin
73
74More detailed description of spl_tool,please refer spl_tool documenation.
75(Note: spl_tool git repo is at https://github.com/starfive-tech/Tools/tree/master/spl_tool)
76
77This will generate u-boot-spl.bin.normal.out file.
78
79Flashing
80~~~~~~~~
81
82SPL loads the U-Boot SPL (u-boot-spl.bin.normal.out) from a partition with GUID type
832E54B353-1271-4842-806F-E436D6AF6985
84
85U-Boot SPL expects a U-Boot FIT image (u-boot.itb) from a partition with GUID
86type BC13C2FF-59E6-4262-A352-B275FD6F7172
87
88FIT image (u-boot.itb) is a combination of fw_dynamic.bin, u-boot-nodtb.bin and
89device tree blob (jh7110-starfive-visionfive-2-v1.3b.dtb/jh7110-starfive-visionfive-2-v1.2a.dtb)
90
91Format the SD card (make sure the disk has GPT, otherwise use gdisk to switch)
92
93.. code-block:: bash
94
95 sudo sgdisk --clear \
96 --set-alignment=2 \
97 --new=1:4096:8191 --change-name=1:spl --typecode=1:2E54B353-1271-4842-806F-E436D6AF6985\

100 /dev/sdb
101
102Program the SD card
103
104.. code-block:: bash
105
106 sudo dd if=u-boot-spl.bin.normal.out of=/dev/sdb1
107 sudo dd if=u-boot.itb of=/dev/sdb2
108
109 sudo mount /dev/sdb3 /mnt/
110 sudo cp u-boot-spl.bin.normal.out /mnt/
111 sudo cp u-boot.itb /mnt/
112 sudo cp Image.gz /mnt/
113 sudo cp initramfs.cpio.gz /mnt/
114 sudo cp jh7110-starfive-visionfive-2-v1.3b.dtb /mnt/
115 sudo umount /mnt
116
117Booting
118~~~~~~~
119
120Change DIP switches MSEL[1:0] are set to 10, select the boot mode to SD.
121Once you plugin the sdcard and power up, you should see the U-Boot prompt.

463Booting from SPI
464----------------
465
466Use Building steps from "Booting from MMC using U-Boot SPL" section.
467
468Partition the SPI in Linux via mtdblock. (Require to boot the board in
469SD boot mode by enabling MTD block in Linux)
470
471Use prebuilt image from here [1], which support to partition the SPI flash.
472
473
474Program the SPI (Require to boot the board in SD boot mode)
475
476Execute below steps on U-Boot proper,
477
478.. code-block:: none
479
480 sf probe
481 fatload mmc 1:3 $kernel_addr_r u-boot.itb
482 sf update $kernel_addr_r 0x100000 $filesize
483
484 fatload mmc 1:3 $kernel_addr_r u-boot-spl.bin.normal.out
485 sf update $kernel_addr_r 0x0 $filesize
486
487
488Power off the board
489
490Change DIP switches MSEL[1:0] are set to 00, select the boot mode to flash
491
492Power up the board.
