MAX32520 takes 7 seconds to boot ???

Category: Software
Product Number: MAX32520

Hi,

So, Im testing the MAX32520 with the EV kit.  Once I flash any of the SDK examples i realized that after RESET the time it takes to boot and execute the code in flash takes about 7 seconds!! My guess is because of the Secure boot loader (SBL), maybe it waits in case you want to send commands to the SBL and then after some seconds jumps to the code in flash ? Now, if that's the case, is there any option to disable this so the flash firmware is executed earlier and you don't need to wait almost 7 seconds ??

Thank you.

  • Found the problem. The MAX32520 with the EV kit comes with the SecureBootLoader command interface enabled. It waits more or less 7 seconds to receive any command over the SBL interface and if nothing is received then boots and executes the flash code. I don't see a way in the documentation to disable this SBL command interface.
