bootstd regression from distro_bootcmd for removable EFI boot and weird return codes for fs
Hi,
I switch to bootstd and I am experiencing an issue with bootstd not detected EFI bootable file in /EFI/BOOT/BOOTAA64.EFI in certain image, buildroot specifically. The same setup works fine with distro_bootcmd. I have attached the logs. I have tried the following:
1) Directory and filename case upper and lower 2) FAT32 and FAT16 filesystem 3) Changing the size of the filesystem
I noticed some particular weirdness with u-boot's return code for functions dealing with fs_exists that might be related.
1) FAT/FAT32 driver uses fs_ls_generic. When you do `ls mmc 1 /filename`, it returns 1 if the file exists and returns 1 when the file doesn't exist. 2) This issue follows fs_exists. Is this a bug or intended behavior?
Best, Da

The issue ended up being the memory allocation. The file was too big (50MB). `bootflow scan -lae mmc1`
In boot/bootmeth_efi.c, bootmeth_alloc_file is set to a pre-defined 32MB so bootefi cannot boot anything larger than that even if you have CONFIG_SYS_MALLOC_LEN set to something larger.
Hope this helps someone.

The file was too big (50MB). `bootflow scan -lae mmc1`
In boot/bootmeth_efi.c, bootmeth_alloc_file is set to a pre-defined 32MB so bootefi cannot boot anything larger than that even if you have CONFIG_SYS_MALLOC_LEN set to something larger.
Hope this helps someone.
Thank you for this. I sent a series[1] to drop the memory allocation, which should resolve this. If you have time to test it, please do!
