wl1273 download firmware errorS

Hi xiang,

Hi,

Could you please specify which WLAN driver are you using and what is the Host?

In addition according to the “tiwlan_drv: no version for "sdioDrv_WriteSync" found: kernel tainted.” Then probably there is an issue with the SDIO driver implementation, which SDIO driver are you using? Is it the one from TI that is part of the package? Or have you have other SDIO driver implementation?

Regards,

Eyal

Hi Eyal,

The module we are using is from Murata.It works well on TI DM365  with the kernel source and WiLink package  provided by Murata.Now i need to port that to our IPNC sys.The SDIO driver is using DM365 SDIO1 with DMA (Supporting 4-bit mode).(It was ported from OMAP2430 i think).

The driver and firmware version are as follows(well worked log ):

.............................................................................................................................................................................................

davinci-mmc davinci-mmc.0: Supporting 4-bit mode
davinci-mmc davinci-mmc.0: Using DMA mode
davinci-mmc davinci-mmc.1: Supporting 4-bit mode
davinci-mmc davinci-mmc.1: Using DMA mode
tiwlan_drv: no version for "sdioDrv_WriteSync" found: kernel tainted.

Though i have modified the corresponding parts with our IPNC kernel(including add MMC1 ,supporting IEEE802.11...),it just hanged with "Starting to download firmware...",maybe still i missed something i think.And any advise would be helpful.again thanks a lot

Hi Xiang,

Sorry for late response, According to the log, the firmware loading is complete, so is it still stuck? Don’t you get a linux prompt any more after you get the Driver/firmware version logs?

Thakns,

Eyal

Hi Eyal,

Thanks for you reply!

My hardware works well with the kernel  and wilink software package from Murata(They ported that from TI released kernel)  ,the good log you saw before is just from this kernel.But our IPNC(IP network camera) kernel is just different from murata's,so we need port that .The follow is the first problem we get during the porting,it hangs on with the third "Starting to download firmware...",

TIWLAN: 1021.212532: Starting to download firmware...

--------------------------------------------------------------------------

and I still think it's the difference between these two kernels which caused that problem.But today i changed the value MAX_SDIO_BLOCK(wilink/twd/fw_transfer/hwinit.c:line 118) from 500 to 420(or smaller),it seems it could finish the firmware downloading but stills hangs as follows:

Atfer this,there is nothing linux prompt any more ,any ideas?and any advise will be appreciated,thanks

Hi Xiang,

As you noticed you are having problems in your SDIO driver.
Please try to removing advanced SDIO features, for instance please start working with:

1. 1 bit SDIO
2. No DMA
3. No Block Mode

Then one by one start testing the 4 bit SDIO then DMA usage then SDIO Block Mode.

Thanks,
Alon.S
