Dear all,
I am newbie in linux usb modules area. I am trying to
port embedded linux kernel (ver. 2.4.26) on
MS7751RCP01 (SuperH 7751R processor based t-engine
like reference board from Renesas).
This board has got NEC's usb 2.0 UHCI host controller.
I am facing followoing problems.
1) This controller is detected by the kernel on boot
time, but it is probing the wrong IRQ. (The IRQ to IRL
is managed by the FPGA), the kernel should allocate
IRQ 9 but the messages says it is IRQ 10
I think you can best solve this by modifying the code for the interrupt
controller (probably somewhere in arch/sh/ ) and map them correctly.
2) I am trying to mount SD Card (MMC) on USB with usb
reader. I have selected the build in option for SCSI
Storage and USB storage related. If i boot the kernel
without this device, it goes fine, but as soon as i
attatch the USB reader with SD card, it hangs (no
panic.. seems that it is in some ageless loop :( )
I would guess its waiting for an interrupt to happen....
