Before power on RB8762CMB, please pull high P0_3_LOG (can use a jumper as
bellow), then power on and last for 15 seconds. The purpose of this step is to make
RB8762C “Not execute” firmware. Connect P0_3_LOG to VDD_3V3 for over 15
seconds to erase the firmware of RB8762C.
Once you erase the firmware code, the module will lose the code forever
until you download new code again. Please use RB8762CEVK
(RB8 RB8762CHM) to get confidence on the procedures of
Erasing and Downloading new firmware first.
