Dear u-boot list,
I recently compiled (latest: 2021.10) code of uboot as a boot loader for the Compute Module 3+ (Raspberry). Everything works fine except one issue: the IO from the storage is extreme slow. I read about issues in the past related to ext file systems. However the present issue relates to both ext and fat file systems so I assume its cause is different.
This is what I did:
U-Boot> setenv pio_kernel "recovery/kernel.img" U-Boot> setenv pio_initrd "recovery/initrd.img" U-Boot> fatload mmc 0:1 ${kernel_addr_r} ${pio_kernel} 5299624 bytes read in 45262 ms (114.3 KiB/s) U-Boot> fatload mmc 0:1 ${ramdisk_addr_r} ${pio_initrd} 24239932 bytes read in 206978 ms (114.3 KiB/s)
The configuration of by build is attached.
Is there anyone else experiencing this kind of issues?
Thank you very much.
Mario
