Internal error: Oops: 805 [#1]
Modules linked in:
CPU: 0 Not tainted (2.6.23-rc4-davinci1 #2)
PC is at cppi_controller_start+0x18/0x140
LR is at musb_probe+0x1f4/0x824
Please try two things:
- In kernel menuconfig, enable
Device Drivers -> USB support -> DaVinci 644x USB support: Disable
DMA (always use PIO)
Does this fix Oops above?
- Try patch (with PIO disabled again/DMA on) as proposed by David in
attachment.
Please let us know if anything like this helps.
Best regards
Dirk
