ath79: sysupgrade will brick devices with RedBoot bootloader
Username: tmn505
Origin: https://bugs.openwrt.org/index.php?do=details&task_id=2428
The current code responsible for upgrading devices with sysupgrade image, doesn’t take in to the account that “FIS” partition and “RedBoot config” partition can be on the same erase block. This can cause erasing the “RedBoot config” partition and make the device inoperable. The recovery would involve external SPI programmer or usage of JTAG.
The cause is still assumption so it will need confirmation. Flashing devices with factory image should be safe.
- Device problem occurs on:
