r3 mini 折腾笔记

 

刷机相关 

 

先切换到nand开机下恢复原厂固件

echo 0 > /sys/block/mmcblk0boot0/force_ro
dd if=bl2_emmc-r3mini.img of=/dev/mmcblk0boot0
dd if=mtk-bpi-r3mini-EMMC-20230719.img of=/dev/mmcblk0

成功后刷入im固件

dd if=gpt.bin of=/dev/mmcblk0 bs=512 seek=0 count=34 conv=fsync
echo 0 > /sys/block/mmcblk0boot0/force_ro
dd if=/dev/zero of=/dev/mmcblk0boot0 bs=512 count=8192 conv=fsync
dd if=preloader.bin of=/dev/mmcblk0boot0 bs=512 conv=fsync
dd if=/dev/zero of=/dev/mmcblk0 bs=512 seek=13312 count=8192 conv=fsync
dd if=bl31-uboot.fip of=/dev/mmcblk0 bs=512 seek=13312 conv=fsync
dd if=recovery.itb of=/dev/mmcblk0p4 bs=512 conv=fsync
dd if=sysupgrade.itb of=/dev/mmcblk0p5 bs=512 conv=fsync

在im固件下刷入nand固件
Boot from EMMC, and get into the uboot command shell.

usb start

ls usb 0:1 – Your File (Image.bin) should show up

fatload usb 0:1 $loadaddr nand-factory.bin

nand erase 0x0 0x8000000

nand write $loadaddr 0 0x8000000

Boot to Nand now working.

风扇：
echo 30 > /sys/class/hwmon/hwmon1/pwm1
