Hi,

We are using fgh100m in our product (Openwrt Router). Sometimes the radio crashes and shows the logs below

It requires power cycle to recover that

Hi @sankarganesh

Are you able to narrow down the conditions which trigger these crashes? So we can attempt to replicate internally.

Taking a guess from the logs - which are showing command timeouts - it could be that the chip has gone to sleep due to an incorrect state of the powersave lines - please use a logic analyser to capture the SPI, Reset, and powersave lines before, during, and after a crash.
