对SD卡的制卡如下:(SD卡格式是exFAT的不知道是否因此和FAT32下有区别)
fanelu@fanelu-virtual-machine:~/work$ sudo dd if=firmware_ls1046ardb_uboot_sdboot_1133_5a59.img of=/dev/sdb seek=8 bs=512
[sudo] fanelu 的密码:
记录了29270+1 的读入
记录了29270+1 的写出
14986242 bytes (15 MB, 14 MiB) copied, 14.3374 s, 1.0 MB/s
对板子上电后打印信息如下:
U-Boot SPL 2018.03 (Dec 08 2021 - 16:27:33 +0800)
Initialzing DDR using fixed setting
Configuring DDR for 2100 MT/s data rate
Trying to boot from MMC1
spl: mmc init failed with error: -110
SPL: failed to boot from all boot devices
### ERROR ### Please RESET the board ###
拔出sd卡恢复AB开关默认设置启动板子会反复的重启
前面部分省略

到这里打印完一轮 下面开始重启往复
