Hi NXP:
One of my projects needs to realize remote software upgrade, and the upgrade part needs to be implemented in the bootloader stage. Only dsbl is found on the official website, and it is an IAR project. My IAR software failed to crack, and the dsbl method provided on the official website cannot be used. I try to use ymodem to realize remote software upgrade. Can I find the Keil based bootloader project?
thank you!
