Hi Eugen, I built new binaries with CONFIG_SYS_THUMB_BUILD=y for sam9x60_curiosity, sama5d29_curiosity, sama7g5ek and new sam9x75_curiosity board. I used the latest u-boot/master branch for this test. I noticed that the file size of the binaries have beed reduced with aprox 150KiB due to CONFIG_SYS_THUMB_BUILD=y. After flashing the new binaries on these boards I can confirm that on all boards the linux kernel was booted properly from mmc, qspi-flash, nand-flash and usb. I tested using bootm and bootz commands.
Best regards, Mihai Sain -------------------------------------------------------------------- On 11/16/23 20:47, Tom Rini wrote: > On Sat, Nov 04, 2023 at 10:27:42PM -0400, Sean Anderson wrote: > >> Several AT91 boards are quite close to their SPL size limit.

Thanks! > Hi Tom, I would like this to be tested on a few boards at least. There are boards with Cortex A5, A7 and ARM926 which are important, one of each of them and booting Linux should be enough I think. Nicolas, Aubin ? I remember you guys have also a CI tool that is fairly easy to use if you just push a branch/commit. + Mihai as well. Eugen
