Hello guys
I have a board of 8247 ,I have get it run with kernel patched with cpm2usb
It seems the irq of usb in 8247 dont work
the proc looks like the follow
bash-3.00# cat /proc/interrupts
CPU0
11: 0 CPM2 SIU Level m82xxhci
32: 0 CPM2 SIU Level fenet
33: 72876 CPM2 SIU Level fenet
40: 389 CPM2 SIU Level cpm_uart
BAD: 5611
And I have seen the same question in the mail list , somebody just say set the correct USBCLK,
i modify the board_configure and setup_usb_clock function , and i make sure the usbclock is correct set
The chipset looks like of Version A.0
bash-3.00# cat /proc/cpuinfo
processor : 0
cpu : G2_LE
revision : 1.4 (pvr 8082 2014)
bogomips : 177.15
Any other Thing should I modify to generate the usb interrupt ?
