Hello,
We are in the bringup process of a new design.It is based on Laird EWB module - STM32F412 + CY4343W architecture.
Everything works well on the dev kit, however on the actual platform, access to the 'WiFi part' of the 4343 either hangs or returns error code.
e.g. - a call to wwd_wifi_get_mac_address() fails.
Tracing the code wwd_wifi_get_mac_address() --> wwd_sdpcm_get_iovar_buffer() -> internal_host_buffer_get() shows that the problem is with some allocation in the following command:
status = nx_packet_allocate( pool, nx_buffer, 0, timeout_ms ); // wwd_buffer.c, line 148 (SDK 6.4)
it returns status==7 which translates to NX_PTR_ERROR.
The very same code works on the dev kit....
One other thing worth to mention - 'BLE part' of the 4343W works flawlessly.
What can be the reason/s for the failure of all 'WiFi calls' on the proprietary hardware??
Thanks for any advice.

For whom it may help in the future - It was a power problem to the 4343W...
