Hello Tim,
you are listed as maintainer of i.MX8MM Venice board in U-Boot.
I am currently working on LTO support for U-Boot, and I have encountered a problem with i.MX8MM Venice board: when LTO is enabled, the linking process for SPL does not throw away relocation information, making the resulting SPL image too big for that board.
I have added a patch that discards symbols from .rela* section to my patch series, but I would like you to test whether the patch series works for your board and does not break anything.
Could you please clone https://github.com/elkablo/u-boot branch lto, build for imx8mm_venice_defconfig and test whether it boots on your board and maybe test some U-Boot commands (disk reads, kernel booting, ...)? If it does not work, could you also please check with current U-Boot master, to see if it got broken with my patches or with something different?
Marek,
Your lto branch does not boot - I don't get anything after the SPL banner. U-Boot master shows the same problem so some regression has taken place.
There should be several other IMX8 boards using SPL that show the same issue I would think?
I will have to bisect to find the breakage.
Marek,
My testing may be flawed as I'm having issues with even the branches I submitted to add my board (which I previously tested without issues). I'm not sure if I'm having a compiler related issue or something else.
Perhaps there is another IMX8 SPL user out there that can test with your patches while I figure out what's wrong on my end?
I have tested and booted an i.MX8M Nano with a slightly older revision of Marek's git repo. I wrongly assumed that the Mini and Nano were close enough to not warrant testing on the mini, but based on what I'm hearing, I will test the Beacon i.mx8mm board. I can try to do that sometime later this week.
