Latest MityDSP-L138 U-Boot image
Added by Mathew Jones over 5 years ago
Hi,
As part of investigating the impacts of the 8MB NOR Flash obsolescence and its 16MB replacement (PCN 20180209000),
I'd like to be able to re-program the latest U-Boot image back onto any MityDSP-L138 SOM.
Do you have a binary image to download for the version currently being delivered on these SOMs
(reported during boot-up as "2009.11-00004-gabfcd69 Jan 03 2018 - 11:30:43") ?
Also, is the latest U-Boot image that supports the 16MB NOR Flash backward compatible on MityDSP-L138 SOMs with the older 8MB NOR Flash?
Thanks
Mat

You can either build the latest u-boot or we do have a yocto based MDK released that has the newer u-boot binary. See the Release 2018.04 in the files section
Note: I've attached the u-boot and uImage shipped with that MDK. They should work without having to reflash the filesystem.
This wiki page can help for flashing a newer u-boot.
Updating devkit to latest MDK

Yes, u-boot patch added support for detecting newer largers NORs. Older NOR is not effected.

Thanks for that quick info.
I've realised that the u-boot.img file you attached is without the UBL header and so it can't be used for in-field upgrades
(but it does work with the Windows Flash programming tool sfh_OMAP_L138.exe).
I downloaded and extracted the Release 2018.04, but unlike previous MDKs I could not find the pre-built file 'u-boot-ubl.bin' (nor u-boot.bin)
Could you attach the file u-boot-ubl.bin?
Much appreciated,
Mat

Hi Mathew,
Jon spoke to me about building the files for you. I've attached the files you were asking for.
