I have a board using a Marvell 8686 wireless lan chip for communication. This chip is connected via SPI and uses libertas / libertas_spi driver for normal operation.

Now I try to put this chip into so called "manufacturing test mode" to enable continuous transmit mode and others.

I try to implement this with the debugfs, which the libertas-driver already has implemented.

Has someone a clue, if this can work?
Do I need a special firmware for doing my tests?
Does someone know any other driver which has implemented such test modes?

Best regards
