Hi..
we are designed one custom board based on the DM8148 EVM. in our custom board we are connecting the tiwi-5 chip to HSMMC1 port using TXS02612RTWR level converter(because processor side 3.3 port is there). we are using PSP04.04 linux kernel 2.6.37. we also applied few patches ,which are given by TI to support wlan on DM8148. we are using compat wireless which is given by ti site.
we are able to load the firmware in wl1273, when we are running the wpa_supplicant some times we are getting sdio_read failed (-110/-84) and some times we getting sdio write failed -110/-84. after that IRQ line is in high state.
sdio_data0 line also some times becoming low for long time. when this is happen ,wifi is not working.
why wlan_IRQ line is always high? we dont know the reason . please help us..
i am attaching the log file
please help us...
Regards
Kishore
