Yes, tried that but didn't work, either of them (the append or the added option to kernel)

Maybe if root is not set in kernel config it would take the u-boot root settings, root= from kernel is appended to root= from u-boot if both sections are present

but even if I changed the config to /dev/mmcblk0p1 or /dev/mmcblk0p2 it will fail, maybe the image is not correctly created ?

I have this fat32 partition 1 and the partition 2 is a 32MB one

I think CONFIG_CMDLINE_FROM_BOOTLOADER is needed for that

jernej how can I have dynamic partitions, I see in config that

CONFIG_CMDLINE="root=/dev/ram0 rdinit=/init"

but then it will fail with

Code

but the u-boot image is booting with

Code

Kernel command line: boot=UUID=0803-5609 disk=UUID=7faabc68-44a0-446a-a69b-dcdcbbf4aaf3 console=ttyS0,115200 console=tty1 root=/dev/ram0 rdinit=/init

can this be set outside of the generic kernel config or per device type so I won't have to change it in the generic one ?

Quote from jernej

removing projects/Allwinner/patches/u-boot folder will help?

a20 lime has by default DFU enabled and it depends on USB that was disabled by 002-disable-usb.patch

I know it will not work by default but we have start from somewhere

jernej

I'm trying an A20 olimex-lime2 image build from your repo, but if I do

Code

PROJECT=Allwinner DEVICE=A20 UBOOT_SYSTEM="olimex_lime2" ARCH=arm make image

then u-boot fails to compile with

Code

it's going on using the u-boot CONFIG_SYS_LONGHELP=y

if I don't pass the BOOT_SYSTEM="olimex_lime2" then the image is empty

in script/uboot_helper to Allwinner I added the entry

Code

'A20' : {
'olimex_lime2' : { 'dtb' : 'sun7i-a20-olinuxino-lime2.dtb', 'config' : 'A20-OLinuXino-Lime2_defconfig' },
'olimex_lime2_emmc' : { 'dtb' : 'sun7i-a20-olinuxino-lime2-emmc.dtb', 'config' : 'A20-OLinuXino-Lime2-eMMC_defconfig' },
},

the other options where taken from H3 board example and the kernel config was completed with a tested working config, beside other kernel patches do I miss something ? I don't see other patches for A20 missing on u-boot, as the board is fully supported

Thanks
