Hi,
Recently, i tried to update the firmware in my Juno r1 board. Specifically, i was trying to use the linaro release script workspace_1801.py with Openembedded LAMP. However, after i copied the content in the "<workspace>/recovery" fold to the MMC card and restarted the board, the boot process is stuck.
In the serial output, it shows the following,
ARM V2M-Juno Boot loader v1.0.0
HBI0262 build 1635
ARM V2M_Juno r1 Firmware v1.3.3
Build Date: Mar 31 2015
Time : 20:43:07
Date: 17:08:2093
I am expecting the output "Press Enter to stop auto boot...", however, no more output is coming out. Moreover, the MMC card is not mounted to the host machine, so i cannot do any further modification to the firmware. I also tried to directly read the plug out the MMC card of the board and read it with an sdcard reader, and it shows that the card is not readable due to some errors. Does anyone happen to know how to fix this? Can i treat the MMC card as a normal sdcard and format it?
Thanks in advance!
Best,
Zhenyu
Hi Zhenyu,
It sound like your copy of "<workspace>/recovery" got corrupted.
Yes you can format the MMC card via your sdcard reader.
Once reformatted you can then copy the "<workspace>/recovery" image onto the card using the card reader before inserting the card back into the board.
We recommend that you run a sync command to ensure the copy is completed before removing the card reader from your PC.
Kind regards
Michele
