New uBoot for PogoPlug V3 question

Hi,

i was playing around with the pogoplug V4 in uboot and found the nice sntp (and other) commands to setup time during boot. I tried that on the Pogoplug V3, but the exisiting SATA uboot version does not support these commands.

I looked at https://forum.doozan.com/read.php?3,16017,page=1 for creating a new uboot to boot from SATA (not for flashing), but it is not very straight forward for me and i have a few question:

1. Can i compile the uBoot from https://github.com/mibodhi/u-boot-oxnas on any computer or it has to happen on an arm device?
2. Is there any base config where i can start from? If not what should i set in the menu config to compile it for oxnas?
3. As i know by default it creates a flashable image. What do i need to change to get a image usable for SATA boot?

I am pretty new for uBoot maybe there is a good guide for it but i did not find it so far.

Thanks

schnee,

I'd recommend that you flash the new u-boot for NAND to use SNTP.

SATA-version u-boot is only a rescue mechanism, in case you need to recover and reflash NAND u-boot.

Thanks Bodhi. I understand that it is considered as rescue mechanism, however i am using it in some cases where i was unable to fix the NAND.....

Can you point me to a guide and probably a config example which could help me to start playing around with uboot?

Thanks

schnee,

I can't recall where others have, and I have not written any guide about rebuilding this particular u-boot.

BTW, this u-boot is not a good vehicle to learn how to patch and rebuild u-boot. I did my best to track mainline code in uboot.2015.10-tld-2 or OX820 (the latest I released here). However, there are substantial differences from mainline u-boot, so I would not recommend using this souce tree as a guide in learning u-boot.

Thanks Bodhi!

i tried compiling your u-boot version. It compiles if it set to nand boot (not tested the result yet), but when i try to build it for SATA i end up with error:

common/built-in.o: In function `initr_ide':
/root/u-boot-oxnas/common/board_r.c:617: undefined reference to `board_start_ide'
ld.bfd: BFD (GNU Binutils for Debian) 2.28 assertion fail ../../bfd/elf32-arm.c:9514
Makefile:1173: recipe for target 'u-boot' failed
make: *** [u-boot] Error 1

I will spend some more time on investigating the issue later.
