I am integrating a RAK4200 module on to a new pcb,
I have configured the PCB as per the recommended configuration from RAKWireless.
According to the schematic of the RAK4600, the Boot0 pin is tied down internally, so I presume that the bootloader image should be written to 0x8000 0000, is this correct?
I am able to program the bootloader image (3.2.3) at this address using the JLink, no issue there.
But I am seeing no activity on UART2 during boot. I also checked UART1
I am not sure what else I may have missed, or what else I need to do to get this unit operational.
I understand that there is a boot image version 3.2.6 to be released soon, do I need to be using that?
I am using 3.2.3
