Hi,

This series updates and adds defconfigs for the recent(ish) atmel boards. They use Atmel's u-boot and kernel tree and are meant to be flashed on the NAND flash.

Alexandre Belloni (8):
configs: update at91sam9g45m10ek defconfig
configs: add defconfig for Atmel at91sam9rlek
configs: add defconfig for Atmel at91sam9x5ek
configs: add defconfig for Atmel sama5d3xek
configs: add defconfig for Atmel sama5d4ek
configs: add defconfig for Atmel sama4d4 Xplained Ultra
configs: add defconfig for Atmel sama5d3 Xplained
configs: rename atmel_xplained_defconfig

That is the expected behaviour. This branch must not break. I'm not saying it won't break but if it ever breaks, it will definitively be fixed.

OK - that is fine as I don't really have a strong opinion on this so leaving it as the branch is fine with me. I was more so making the observation.

That is the expected behaviour. This branch must not break. I'm not saying it won't break but if it ever breaks, it will definitively be fixed.

No, please don't use a branch. Never ever. This makes the build non-reproducible. And also means that once a linux-linux-3.18-at91.tar.gz tarball has been created in $(DL_DIR), it is never redownloaded even if the branch is updated.

So please do like Ryan said: use a tag or a commit ID. Feel free to update this commit ID or tag as often as you want by sending patches, but don't use a branch name.

Thanks,

Thomas

PATCH 8/8 configs: rename atmel_xplained_defconfig

In reply to Alexandre Belloni

For consistency, rename atmel_xplained_defconfig to atmel_sama5d3_xplained_mmc_defconfig as this configuration supports booting the sama5d3 Xplained with an MMC card (as opposed to the NAND flash).

I believe the readme.txt under board/atmel/xplained should be updated to say atmel_sama5d3_xplained_mmc_defconfig instead of atmel_xplained_defconfig.

Thanks

Indeed, I'll update it.

cover configs: defconfigs for Atmel boards

In reply to Alexandre Belloni

Hi Alexandre,

Quoted 16 lines · Alexandre Belloni

Hi,

This series updates and adds defconfigs for the recent(ish) atmel boards. They use Atmel's u-boot and kernel tree and are meant to be flashed on the NAND flash.

Alexandre Belloni (8):
configs: update at91sam9g45m10ek defconfig
configs: add defconfig for Atmel at91sam9rlek
configs: add defconfig for Atmel at91sam9x5ek
configs: add defconfig for Atmel sama5d3xek
configs: add defconfig for Atmel sama5d4ek
configs: add defconfig for Atmel sama4d4 Xplained Ultra
configs: add defconfig for Atmel sama5d3 Xplained
configs: rename atmel_xplained_defconfig

Since you are moving all of the Atmel boards to use NAND boot configuration, it would be good to have a 'README' that explains how to load the boards utilizing the SAM-BA tool (it appears all the NAND configurations are using this). At minimum it would be to point to Linux4SAM wiki for loading instructions.

Thoughts?

Thanks,
-Ryan

Sure, I'm actually planning to provide the tcl scripts to use with SAM-BA to help people load the generated images on their board.

Fully agreed.

Alexandre, please also include generating a NAND capable filesystem image as part of those defconfig, so that they can easily be flashed/used on the boards. I guess UBI images is going to be the most appropriate solution. But clearly, such defconfigs should not generate just a tarball.

Thanks

Actually, I think it's better to use SD card images where possible.

- If you're using it just for experimentation, then the SD card is a much more flexible and less risky way to experiment. Personally, I even prefer kernel-linked-with-initramfs (and DTB) images, since that's just a single file and it automatically gives you the rest of the SD card as a FAT partition.

- If you want to use it for an actual product (prototype), then you're anyway going to have to study in a bit more detail how the flash works and you'll probably want to do a slightly more complicated flash partitioning.

That said, I do think it's really useful to have those tcl scripts for using
SAM-BA.

And of course, since I never use the defconfigs myself, my opinion is probably
not that important.

Regards,
Arnout
