CC2340R5: CC2340 TI Bootloader

Part Number: CC2340R5

Dear all,

We are trying to activate default TI Bootloader. To do this we configure CC2340 module in this way:

It is a little bit strange becuase in REGISTERS view we see this:

So seems that BOOT Vector table is not properly configured. We are not able to get the basic BAUDRATE DETECTION interaction of sending two 0x55 and get as a ack 0x00CC.

Do you have more information? There is any windows app tool to test this automatically? (as in chipset CC26xx).

Thanks,

Hello Albert,

Can you provide me a zoomed-out image of the ccfg register, so I can see where you are accessing it from? Within the registers view, I am not able to see any additional information within the ccfg register from the register view.

Thanks,

Isaac

Dear all,

Finally following this flow we get a positive response:

DIO25 -> 1 (Boot custom pin)

nRST -> 0

nRST -> 1

delay around 100ms

transmit 0x5555 at 115200

0x00CC is received

Thanks,
