Hi All,

I have RB433 board which failed to boot up.
LD501, LD502,LD503 & LD504 remain ON after power.

I have used the reset button and S301 but no result.
Please advice!

I have couple of device with similar symptoms, if button not help to load backup boot loader usually processor is broken.

Try first with netinstall via serial
