Could not set Country code, WWD_WLAN_BADARG / WICED_DISABLE_MCU_POWERSAVE

EdMA_4611511 · ‎Feb 14, 2020

Hi,

I have an issue during wiced_init() => "Could not set Country code"

I get retval = WWD_WLAN_BADARG while calling " retval = wwd_sdpcm_send_iovar( SDPCM_SET, buffer, 0, WWD_STA_INTERFACE );",

Below a description of my software & Hardware and a Log

Hardware :

- Custom board with an BL6212 and an STM32F412ZG
- Wifi chip is connected through SDIO, without "WL_HOST_WAKE / WL_IRQ / OOB" connected on "WWD_PIN_SDIO_OOB_IRQ / RC6" .

=> "#define WICED_DISABLE_MCU_POWERSAVE" is Uncomment.

Note : I am not sure if "WICED_DISABLE_MCU_POWERSAVE" is supported because in Wiced Eclipse IDE Version 6.4 if I uncomment "#define WICED_DISABLE_MCU_POWERSAVE" in "wiced_defaults.h / L246" and I try to compile : "snip.scan-BCM943438WCD1" => I got compilation errors.

Sofware

- Wiced SDK 6.4

- IAR (I have migrate the code to IAR, so my issue can also come from that).

Below a Log,

Notes :

- WWD_LOG is active, so we have trace of SDIO transfert.

- The "return retval" after "WPRINT_WWD_ERROR(("Could not set Country code\n"));" is commented, so the firmware continue even if SET country failed.

- I ove log wwd_sdpcm_send_ioctl() retval on errors :

Ok, when I wire WL_IRQ / WL_HOST_WAKE and enable WICED_DISABLE_MCU_POWERSAVE it works.

So I had 2 issues :

1/ I didn't define WWD_DOWNLOAD_CLM_BLOB

2/ define WICED_DISABLE_MCU_POWERSAVE / use of WWD_PIN_SDIO_OOB_IRQ pin is required.

EdMA_4611511 · ‎Feb 14, 2020

Note :
- I use the firmware "43438A1.bin" available in "WICED-Studio-6.4\43xxx_Wi-Fi\resources\firmware\43438"

- But I didn't define "WWD_DOWNLOAD_CLM_BLOB"

I did imagine NVRAM is enough, but I might be wrong, does CLM_BLOB is also needed ? What is the difference ?

GauravS_31 · ‎Feb 17, 2020

You need CLM blob to ensure that the country code is set in the CLM. The CLM blob file should be present in \resources\firmware\43438\43438A1.clm_blob. And the WWD_DOWNLOAD_CLM_BLOB should be enabled to allow WICED to download the .clm_blob file to the 43438 radio. By default, this is defined in WWD.mk. The ccode from the NVRAM file is set in the CLM blob. In any case, the clm_blob file is required.

EdMA_4611511 · ‎Feb 17, 2020

Thanks, for your reply.
Yes, when clm_blob is uploaded I have a correct wiced_init() with the debugger in step by step mode.

To be able to run correctly the wiced_init() in standard execution mode I need to add delay between SDIO write/read.

With this fix, when the "scan" demo start I have only the first 3 wifi SSID.

So I think I had 2 bugs :

1/ I didn't upload clm_blob.

2/ WL_IRQ / WL_HOST_WAKE is required.
