08:40 <Luker> I have a u-boot in a raspberrypi4 that can't boot drives >2TB. I tried recompiling with CONFIG_LBA48=1 CONFIG_SYS_64BIT_LBA=1 but it did not help. Should that be supported? whatshould I check/try?

08:40 <Luker> the error it gives is "gpt partition table header signature is wrong"

08:40 <Luker> and only happens with drives > 2TB

08:53 <replayer> when i compile uboot for x86_64 according to: https://u-boot.readthedocs.io/en/stable/board/emulation/qemu-x86.html will it still contain 16 or 32 bit code ?

08:55 <replayer> seabios for example does: https://www.seabios.org/Linking_overview (minus 64 bit)

09:28 <crb> how do I define scripts that evaluate other variables at run time. When I used setenv program "fatload mmc 0 ${fpga_addr} ${fpga_file}" it seem to evaluate the variable at the time of setting the program variable instead of when program is run

11:58 <PoroCYon> hi, I've been writing a u-boot script with some for loops to check for multiple alternative paths (eg. / vs /boot ), and, it works but u-boot doesn't seem to recognise the "break" command, thus keeping on checking for kernel images etc. as I couldn't find any documents on conditionals and loops in its scripting language, I'm asking: how do I break a for loop in a u-boot script?

12:29 <Tartarus> PoroCYon: check out how the distro_bootcmd logic does it, but in short no there isn't break, when you find something you move on to the next step in your logic, so you need to rethink/rewrite with that in mind and unwind logic as needed

12:30 <PoroCYon> ah ok, I see, thanks

14:46 <replayer> can 32 bit uboot boot 64bit kernel?

15:24 <replayer> is there any way to boot the uncompressed kernel with u-boot on qemu?

15:49 <cambrian_invader> crb: use single quotes

16:08 <cambrian_invader> replayer: bootelf?

16:13 <replayer> cambrian_invader: thx

16:13 <replayer> that at least does something but brings me back to the question if 32bit uboot can boot 64 bit kernels

16:14 <cambrian_invader> probably not, in the general case

16:16 <replayer> :/

17:10 <replayer> when i try a 32bit kernel + 32 bit uboot i get "invalid opcode"; any ideas? i used the qemu 32 bit default config for uboot but removed efi support, is that required ?

17:15 <replayer> ok, it is maybe related to not using bzimage. using bzimage + zboot works

17:15 <replayer> i.e. bootelf has some problewms

17:20 <replayer> also booting 64bit kernels on 32bot uboot works then

17:23 <replayer> any ideas why bootelf does not work and gives invalid opcode? or another way to avoid using a compressed kernel image?

17:48 <ecrn> uncompressed Image can be used as a legacy u-boot image with bootm, I think bootz also can boot it

17:48 <ecrn> of course the u-boot image must be created with mkimage

22:36 <sjg1> Tartarus: FYI I am fiddling with a series to clean up Makefile and drivers/Makefile so there are fewer rules and most of the drivers/ stuff is in drivers/Makefile
