My warmest spring hello to all fellow raccoons!
A quick one:
What is the CLM blob and why the 43362 does not require one?
I am using WICED SDK v6.1.
I have observed that if I compile, for example the scan snip, with the debug option I get a failed assertion in:
0x0802609e in host_buffer_release (buffer=0x0, direction=WWD_NETWORK_RX) at WICED/network/NetX_Duo/WWD/wwd_buffer.c:189
189 wiced_assert( "Error: Invalid buffer\n", buffer != NULL );
(gdb) bt
#0 0x0802609e in host_buffer_release (buffer=0x0, direction=WWD_NETWORK_RX) at WICED/network/NetX_Duo/WWD/wwd_buffer.c:189

#7 0x080150b4 in _tx_thread_shell_entry ()
Solved! Go to Solution.

The firmware for WICED devices includes information regarding regulatory constraints. For certain devices this information is kept separately in a binary form also known as CLM blob. CYW43362 has the CLM integrated into the WLAN firmware so it does not require a separate CLM blob. The assertion failure occurs because 43362 does not support "clmver" IOVAR.
