OTHERS: Rock Pi 4A – 固件下载

~ 发表回复
  • 通过USB下载固件

1。进入rockusb 模式

2。使用 rkdeveloptool工具下载

  • rockusb模式

在rockusb模式下，可通过rkdeveloptool：

– 对eMMC/sdcard/SPI nor flash做读写操作

– 可获取存储设备信息

– 获取分区表信息

– 获取芯片信息

– 重启

进入rockusb模式的方法：

1。 通过maskrom模式进入：

– 通过rkdeveloptool 加载bootloader (rk3399_loader_v1.12.112.bin) 进入rockusb模式

$ ../rkbin/tools/rkdeveloptool db rk3399_loader_v1.12.112.bin

2。通过u-boot中的rockusb命令进入

  • 固件下载

对于只使用sdcard作为启动设备的情况，目前看来只能通过先将idbloader.img, uboot.img及trust.img通过读卡器写入到sdcard：

如：

#! /bin/bash

dd if=/dev/zero of=/dev/sdc bs=$((1024*1024)) count=16 conv=notrunc

dd if=idbloader.img of=/dev/sdc bs=512 seek=$((0x40)) conv=notrunc
dd if=uboot.img of=/dev/sdc bs=512 seek=$((0x4000)) conv=notrunc
dd if=trust.img of=/dev/sdc bs=512 seek=$((0x6000)) conv=notrunc

写入完之后，第一次开机如果找不到gpt分区表，会重新创建分区表：

可以看到，之后可以进入到u-boot命令行交互模式。

注：

1。 从目前来看，从maskrom模式进入rockusb模式时，可能只能读写eMMC设备，并且也没有找到相关的命令使rkdeveloptool写入到特定的设备。

2。通地rkdeveloptool加载rk3399_loader_spinor_v1.15.114.bin 应该是对SPI flash进行读写操作（我手头上这块板子虽然是v1.4的版本，但没有SPI flash，无法验证。

3。在这种模式下，看起来CPU与DDR在全速运行，需要注意散热。

=> mmcinfo

Manufacturer ID: 3
OEM: 5344
Name: SC32G 
Timing Interface: Legacy
Tran Speed: 50000000
Rd Block Len: 512
SD version 3.0
High Capacity: Yes
Capacity: 29.7 GiB
Bus Width: 4-bit

3。mmc list

=> mmc list
dwmmc@fe320000: 1 (SD)
sdhci@fe330000: 0

4。rockusb (进入rockusb 模式）

=> rockusb 0 mmc 1
RKUSB: LUN 0, dev 1, hwpart 0, sector 0x0, count 0x3b72400

这时，我们就可以通过rkdeveloptool对sdcard进行读写操作了，如：

$ time ../rkbin/tools/rkdeveloptool rl 0 0x80000 sdcard_256MiB.bin
Read LBA to file (100%)

real	0m20.799s
user	0m0.254s
sys	0m0.982s

读写速度差不多在12MiB左右。
