Part Number: CC2640R2F
Other Parts Discussed in Thread: LAUNCHXL-CC2640R2,

Tool/software: TI-RTOS

I download the sample code:simple_peripheral_oad_onchip

EVM:LAUNCHXL-CC2640R2

I found that EVM boot into OAD mode,

I hope that the normal operation of the boot code, through the external trigger into OAD mode.Do you have any suggestions? Do you have the sample code?

Well, I'm not really sure I completely understand your question. OAD is triggered by writting to the OAD profile which will determine if the image that's being written to it is valid. As soon as the image download is complete, a reset will be triggered programmatically which will then automatically jump to the BIM to check BIM val.

can you please clarify what you are trying to do?

Hi Evan

Current status: After power on, the CC2640R2F enters into the OAD presisent status.

My demand:After power on,the CC2640R2F do not enter the OAD presisent status. After some way of triggering, then enter the OAD presisent status

How should this code be set?

The Hank,

The Persistent App is required for On-Chip OAD Application. See, also Off-Chip OAD which does not use Persistent App.

Hi,

The device must always boot into the BIM after a reset. The reason you cannot just jump there is because c runtime must be re-initialized. The BIM var is set when the OAD reset service is written to and a OAD RESET event has been generated and processed.
