No uboot in /root #2

Open Bleifusshamster opened 1 year ago

Bleifusshamster commented 1 year ago

HI, I'm facing problem while set up MR42 for OpenWRT. Performing the JTAG to flash way I'm not able to do step 5 ("(MR42 only) Do not connect over the network") due to get response from device of "failed to find mtd-rw. maybe it is a built in module?". Furthermore /root on MR42 is empty, no uboot inside. The transfer handled by python script seems to be successful due stop with done and OpenWRT is starting on device (without ethernet support, eth0 is down).

I'm using the mr42_u-boot.bin running on TFTP server with address 192.168.1.250 hosting files "openwrt-ipq806x-generic-meraki_mr42-initramfs-fit-uImage.itb" and "mr42_u-boot.mbn"

May you able to help me whats my fault? Cheers!

This is a rather old issue, so a note for others in this situation -

Transfer the file over serial TTY. You can find methods here and here.

@Bleifusshamster What tutorial are you following?

I also have this issue. The OpenWRT initramfs doesn't have xmodem/zmodem/kermit or even base64. What is the best way of doing this?

Hi,

I had the same issue. My solution was to transfer base64 encoded files over serial:

I had to repeat this process for the U-boot binary, the mtd-rw ipk, the nand-utils ipk and the sysupgrade (!) binary.
