I have my own build root for openwrt snapshot.
Some strange behavior
normally I burn the image using this script to sd-card directly in ubuntu
gunzip bin/targets/mediatek/filogic/openwrt-mediatek-filogic-bananapi_bpi-r3-sdcard.img.gz sudo dd if=bin/targets/mediatek/filogic/openwrt-mediatek-filogic-bananapi_bpi-r3-sdcard.img of=/dev/sdd
but these card will not boot in my R3 v1.1
ERROR: MSDC: CRC error occured while reading data with cmd=17, arg=0x680000 ERROR: MSDC: Command has timed out with cmd=17, arg=0x680000 ERROR: BL2: Failed to load image id 3 (-5)
Regarding the reported crc-error in bootlog, the dd command only says
909701828 bytes (91 MB, 87 MiB) copied, 19.6752 s, 4,6 MB/s (no error)
If I use win32imager in Win11 with the same image to write the sdcard, all is fine. Edit: just found, the image is also not usable in Windows. Wondering, just yesterday that was the solution.
So I must have the bug in my buildroot. I changed the root partition size to 512 MB and added several packages. During make process I can´t see any errors. Do I have wrong build options?
