Hi everyone,
I’m a beginner just starting out and I’m stuck on this and I hope you can help me.
I just got a Banana Pi Bpi R4 and I’m having problems with the emmc. I copied the “. img” files to the emmc (booting from NAND) as it says on the Banana pi page/tutorial and it worked but I made a bad ppoe configuration and I couldn’t access the router through luci or ssh anymore. I tried pressing the reset button to erase the configuration but it didn’t work and I even tried to copy the “. img” files again but it still didn’t work. I used fdisk to delete mmcblk0 and copied again and it didn’t work.
Is there any way to completely erase mmcblk0 and mmcblk0boot0 to start over?
I understand that the emmc and SD use the same path and when I start with the SD card it does start and works but with emmc it doesn’t give me a signal by ssh or luci although it does detect the ethernet cable because it turns on the port light.
I used this code to copy to emmc and use the Openwrt MTK MP4.0 files from Banana Pi
echo 0 > /sys/block/mmcblk0boot0/force_ro dd if=bl2_emmc-r4.img of=/dev/mmcblk0boot0 dd if=mtk-bpi-r4-EMMC-20231030.img of=/dev/mmcblk0 mmc bootpart enable 1 1 /dev/mmcblk0
Is there a difference in performance when using SD, NAND and EMMC?
I already ordered the USB UART from aliexpress but it would arrive in about 3 weeks so right now using UART is not an option. Is there a way to use Openwrt FIP and BIN files without using the UART port?
