radxa Rock 5B rk3588 buildroot 编译

rockchip RK3588 Rock 5B 开发板-启动

硬件：RK3588 Rock 5B
软件: Rock 5B U-Boot 2017.09, linux 5.10.110-gd29d8a1f1f33-dirty
问题
硬件: 散热小风扇 2W, Rock 5B 16G-RAM, 256G 固态硬盘, 65W DP 充电器, 诱骗稳压器(正点原子 DP100)

1.重启问题

	我使用小米的67W充电器 Type-A（5V 3A），多数时间启动过程中重启，且一直循环。
    官方信息：USB Type‑C™ PD Version 2.0 with 9V/2A, 12V/2A, 15V/2A and 20V/2A.

2

• Power adapter with fixed voltage in 5V to 20V range on the USB Type‑C port
• 5V Power applied to the GPIO PIN 2 & 4
The recommended power source should be able to produce, at least, 24W without a M.2 SSD or 30W
with a M.2 SSD.
注意: 我这边使用方案为普通 DP电源 65W（5V 3A, 9V 3A, 12V 3A, 15V 3A, 20V 3.25A） + DP100（正点原子）诱骗到20V 然后降压到12V 使用。看电影功耗在7W（12v, 0.6a） ～12.5W(12v, 1.2)，跟网络关系很大，在使用浏览器时功耗较高。

2.buildroot 问题

	A. 使用在buildroot 中指定 Rock 5B 的uboot, kernel. 后出现打包 idbloader.img 失败。 
	 原因：使用，buildroot 编译出的uboot-tools(mkimage) 不支持 rk3588,需要使用 rock 5b uboot 下的 /tools/mkimage 做打包
	B. ubuntu22.04 编译打包 BL31 时调用python 失败(该错误不会导致编译失败，需要谨慎)
	 原因：ubuntu 22.04 默认安装的是 python3(python3.10 需要降级到 python3.8), uboot 内部打包 BL31 的python 脚本指定是 python。需要将python 链接到python3

3.NVME 盘启动问题

	A. uboot 通过 ctrl+c ，进入命令行（如果无法进入，请在uboot 内部将 stdin disable 关闭 CONFIG_DISABLE_CONSOLE ），然后首先输入 pci enum 查找到设备。然后再进行 nvme scan, nvme info 扫描

4.WIFI 网卡无法启动问题

我是用的是 rtl8852be ,但是网卡无法扫描到设备, 蓝牙不能使用
1

该版本中有wifi rtl8852be 驱动错误
/kernel-linux-5.10-gen-rkr3.4/drivers/net/wireless/rockchip_wlan/rtl8852be/phl/phl_cmd_ser.c 修改如下即可

_phl_ser_mdl_init
	pq_init(drv, &cser->stslist); # 添加 修复bug
_phl_ser_mdl_deinit
	pq_deinit(drv, &cser->stslist); # 添加 修复bug

5. RK3588 U-Boot编译报错

U-Boot 2017.09 编译时，需要使用到python, 但 ubuntu 默认安装python3 (python3.10 降级到 python3.8)需要 ，需要ln -s [python3] [python]链接。
U-Boot 编译产生 u-boot.itb, u-boot-spl.bin 两个文件，在后面要用到(需要通过u-boot-spl.bin 合成 idbloader.img), rk3588_ddr_lp4_2112MHz_lp5_2736MHz_v1.08.bin 文件由官方SDK 提供(注意: mkimage必须使用RK 提供的uboot/tools下的工具)

U-Boot-2017.09/tools/mkimage -n rk3588 -T rksd -d board/radxa/rock-5b/rk35/rk3588_ddr_lp4_2112MHz_lp5_2736MHz_v1.08.bin:$BINARIES_DIR/u-boot-spl.bin $BINARIES_DIR/idbloader.img

6. 编译U-Boot/Kernel 时出现错误

原因Ubuntu22.04 安装gcc 版本为 gcc version 11.3.0 (Ubuntu 11.3.0-1ubuntu1~22.04.1)
解决方式: 降级 gcc 版本到 gcc9

/usr/bin/ld: scripts/dtc/dtc-parser.tab.o:(.bss+0x10): multiple definition of `yylloc'; scripts/dtc/dtc-lexer.lex.o:(.bss+0x0): first defined here

出现某些dts文件编译报错直接修改u-boot/arch/arm/dts/Makefile将报错的dts 删除
