Hi everyone,
My development board has two memory banks, SDRAM (128MB) and PSRAM (16MB). I've got the linux kernel booting from only the PSRAM, but I can't get a USB Flash Drive to work properly. It is being detected, but I get the following messages:
--------------------------------------------------------------- usb 1-1: reset high speed USB device using fsl-ehci and address 4 sd 2:0:0:0: [sda] Result: hostbyte=0x05 driverbyte=0x00 end_request: I/O error, dev sda, sector 0 Buffer I/O error on device sda, logical block 0
---------------------------------------------------------------
This ONLY occurs when I use the PSRAM on the board. I've made no changes to the drivers and my changes to kernel source were minimal. I only changed the following (zreladdr, param_phys-y, PHYS_OFFSET).
I'm at a complete loss on how to fix this but it's critical for me to use PSRAM. Any help is greatly appreciated.
Thanks!
