[Solved] 19.07.xx own build unflashable

For Developers
1

I have a MVEBU EspressoBin Board in official 19.07.03 for emmc v7.
I want to add some feature to the kernel (lxc, quota, acl) so I build my own OpenWRT firmware image from the 19.07. branch.

I get n error while trying to flash my image :
2020-08-21_11-14

What am I making bad ?

If I try to make a force upgrade, nothing is flashed at all...

let me guess... the image you are trying to flash ( via luci sysupgrade ) has;

  • img
  • no sysupgrade
    and
  • sdcard

in it's name?

the name was the default one, I reflash with a hard command line :
zcat /dev/mmcblk0 < img.gz

openwrt-mvebu-cortexa53-globalscale_espressobin-v7-emmc-ext4-sdcard.img.gz

Still unflashable from a 19.07-master and also a 19.07.3 self built !?

unflashable board :

root@NAS:~# cat /proc/cmdline 
console=ttyMV0,115200 earlycon=ar3700_uart,0xd0012000 root=/dev/mmcblk0p2 rw ip=0.0.0.0:0.0.0.0:10.4.50.254:255.255.255.0:marvell:eth0:none nfsroot=0.0.0.0:/dev/mmcblk0p2

correct board :

root@LPM:~# cat /proc/cmdline 
console=ttyMV0,115200 earlycon=ar3700_uart,0xd0012000 root=/dev/mmcblk0p2 rw rootwait net.ifnames=0 biosdevname=0

test :

root@NAS:~# fw_setenv bootcmd 'mmc dev 1; ext4load mmc 1:1 $kernel_addr $image_name; ext4load mmc 1:1 $fdt_addr $fdt_name; setenv bootargs $console root=/dev/mmcblk0p2 rw rootwait net.ifnames=0 biosdevname=0; booti $kernel_addr - $fdt_addr'

reboot

then:

root@NAS:~# cat /proc/cmdline 
console=ttyMV0,115200 earlycon=ar3700_uart,0xd0012000 root=/dev/mmcblk0p2 rw rootwait net.ifnames=0 biosdevname=0


root@NAS:~# sysupgrade -T openwrt-19.07.3-mvebu-cortexa53-globalscale_espressobin-v7-emmc-ext4-sdcard.img.gz
