CC2340R5: Is there a way to speed up MCUBoot?

Shuyang Zhong

Part Number: CC2340R5

MCUBoot takes a relatively long time to validate the image and start. I already remove the blink LED part after the validation succeeds, but it still takes about 2s to start. Is there a way to decrease the time further?

Best regards,

Hi Shuyang,

Thank you for reaching out. To confirm, which SDK is the customer using? Is this happening on a LaunchPad or a custom board?

Best Regards,

Jan

Hi Jan,

I tested it on simplelink_lowpower_f3_sdk_7_10_00_35 with a CC2340R5 LaunchPad. I measured the GPIO output on the red LED pin which is pulled high at the beginning of MCUBoot and pulled down in the application code. The duration was 1.98s.

Best regards,

Shuyang
