Wl12xx on imx6 with SDIO power issue

Hi Vishwa,

This suggests that the WLAN IRQ lines are not mapped correctly in your board file...
Please follow: http://processors.wiki.ti.com/index.php/WL127x_Porting_Guide for the wl12xx porting guide.

Regards,
Gigi Joseph.

Hi Gigi Joseph,

Thank for your kind replay.

Now i am unable to bring up the wl1271 interface the second time on imx6

We have ported the TI WL1271 driver to the i.MX6S platform and are using it with Linux3.0.35 reference sabersd. We can enable and disable the Wi-Fi interface for the first time. On trying to enable the wlan interface for the 2nd time it gives the following error log:



wl1271: ERROR timeout waiting for the hardware to complete initialization
wl1271: ERROR timeout waiting for the hardware to complete initialization
wl1271: ERROR timeout waiting for the hardware to complete initialization
wl1271: ERROR firmware boot failed despite 3 retries
ifconfig: SIOCSIFFLAGS: Input/output error


mmc1: Timeout waiting for hardware interrupt.
wl1271: ERROR sdio read failed (-110)
wl1271: ERROR sdio write failed (-84)
mmc1: Timeout waiting for hardware interrupt.
wl1271: ERROR sdio read failed (-110)
wl1271: ERROR chip id doesn't match after firmware boot
mmc1: Timeout waiting for hardware interrupt.
wl1271: ERROR sdio read failed (-110)
wl1271: WARNING unsupported chip id: 0x1
wl1271: ERROR firmware boot failed despite 3 retries
ifconfig: SIOCSIFFLAGS: No such device


Below is my boardfile for imx6s.

Hi Vishwa,

Please check: http://e2e.ti.com/support/wireless_connectivity/f/307/t/181835.aspx
It deals with a similar issue as yours.

Regards,
Gigi Joseph.

Hello Vishwanath Raju,

We're facing a similar issue while we try to bring up the TiWi-BLE module for WiFi on i.MX6 custom board. (kernel version -3.0.35).

Did you get the solution for this problem? It would help us if you could share the information.

Thanks,

Silvy.

Hi Silvy,

Built in driver for wi-fi is not working for me.. I used external driver source and complied for IMX6 as a module and loaded then its worked for me.

Hi Vishwa,

Our BSP is based on Sabresd downloaded from freescale and the kernel version is 3.0.35.
We  also compiled the wi-fi drivers(wl12xx.ko,wl12xx_sdio.ko) as modules, still issue is there..
may i know which kernel version and BSP you are using?

Thanks,
Silvy

Hi Silvy,

I am using the same linux kernel 3.0.35.

Could you brief the issue with log exactly.

Hi Vishwa,

While booting it shows the following message, seems that the device is detected.
[ 3.393043] mmc1: queuing unknown CIS tuple 0x91 (3 bytes)
[ 3.401764] mmc1: new SDIO card at address 0001

Also while loading the drivers some transactions are happening on the mmc1, but not sure it is correct or not..
But if we use the command ifconfig wlan0 up some error messages are shown and we noticed that the mmc1 clock value is set to zero.

Logs are attached.
