Hello,
I would like to use a newer version of the PSP on our product so I tried to upgrade from the psp03.01.01.39 (kernel 2.6.32.17) to the PSP-SDK-03.21.00.04 (kernel 2.6.37). Unfortunately there is a big regression that usb ethernet dongles does not work on the newer version. I have tried eth dongle with mcs7830 chip inside and wifi dongle with RTL8187vB using dm365 evm kit. Drivers for both are included in the kernel. Enabling them is the only difference with the delivered configuration for dm365 evm.
I can enable these interfaces from the command line and they even got an address from the DHCP. But when I try to do anything on the network (ping, wget, ...) the interface hangs and command ifdown eth1/wlan0 causes whole kernel to hang with no error message. I'm not sure if the problem is in the usb driver or somwhere in the linux network support but I expect the first one. Eth0 on the evm works fine, but usb mass storage works correctly as well.
Could please someone help me with this issue?
with best regards
Jan
