On Mikrotik SPI NOR devices, the firmware partition must be erased when flashing from stock firmware, otherwise leftover bits (in particular a kernel signature) can trigger a boot loop. When booted from initramfs (the only way to install OpenWRT on these devices), this patch unconditionally erases the firmware partition in the do_upgrade() stage for all supported SPI NOR devices. This is forward-ported from ed49d0876 and 20452a8db Signed-off-by: Thibaut VARĂˆNE <hacks@slashdirt.org> --- target/linux/ath79/mikrotik/base-files/lib/upgrade/platform.sh | 2 ++ 1 file changed, 2 insertions(+)
