Hi,
I am working on porting the WiFi driver for CYW4343 on a custom board using the reference from WICED SDK.
We are following the sequence of commands found in the API wwd_management_wifi_on() of wwd_management.c and I have successfully downloaded the chip firmware.
I get retval = WWD_WLAN_BADARG while calling "wwd_sdpcm_send_iovar( SDPCM_SET, buffer, 0, WWD_STA_INTERFACE )", where the country code is set as WICED_COUNTRY_UNITED_STATES. I have attached the code snippet below for reference.
We tried to verify the firmware loading by using wwd_wifi_get_wifi_version API and I am able to read the FW version as shown below:
wl0: Apr 30 2018 04:14:19 version 7.45.98.50 (r688715 CY) FWID 01-283fcdb9
But, set country code still fails. Can anyone please help me if I am missing anything. Thanks in advance for your help.
country_struct = (wl_country_t*) wwd_sdpcm_get_iovar_buffer( &buffer, (uint16_t) sizeof(wl_country_t), IOVAR_STR_COUNTRY );
if ( country_struct == NULL )
{
wiced_assert( "Could not get buffer for IOCTL", 0 != 0 );
return WWD_BUFFER_ALLOC_FAIL;
}
memset(country_struct, 0, sizeof(wl_country_t));
ptr = (uint32_t*)country_struct->ccode;
*ptr = (uint32_t) wwd_wlan_status.country_code & 0x0000ffff;
ptr = (uint32_t*)country_struct->country_abbrev;
*ptr = (uint32_t) wwd_wlan_status.country_code & 0x0000ffff;
country_struct->rev = (int32_t) ( ( wwd_wlan_status.country_code & 0xffff0000 ) >> 16 );
/* if regrev is 0 then set regrev to -1 so the FW will use any NVRAM/OTP configured aggregate
* to choose the regrev. If there is no aggregate configured then the FW will try to use regrev 0.
*/
if ( country_struct->rev == 0 )
{
country_struct->rev = -1;
}
retval = wwd_sdpcm_send_iovar( SDPCM_SET, buffer, 0, WWD_STA_INTERFACE );
if ( retval != WWD_SUCCESS )
{
/* Could not set wifi country */
WPRINT_WWD_ERROR(("Could not set Country code\n"));
return retval;
}
