Hi everyone. I'm reaching out to the developers and the community for some guidance. I attempted to manually edit the FIP to expand the memory limit, as the default 30MB was insufficient, but the process failed. I've had to use mtk_uartboot to recover. Could anyone provide advice on how to properly handle this or help me restore the device to a working state? Thanks in advance.
boot initramfs via mtk_uartboot, if you extended/moved the partitions(s) restore your backups.
I restored my partitions also. I want a normal U-boot layout without UBI1
Tried to do the same and brick my mr85x. mtk_uartboot to original fip(cut from mtd0.boot at 0x20000 til the end) with bl2_ram cant see the nand. Non-original fip boots and can save/write/dump nand (mtd also works) but cant see the network. I placed via ymodem all 128mb flash (tried to reflash via programmer with same result) caused stuck when bl2 must locate the fip (bl31). Can anyone help to proceed to the stock -> openwrt firmware? 3 sleepless nights.
P.S. the initramfs loaded by tftp stuck on spi-nand init even where no ubi / mtd in env bootagrs given.
