LPC55s36 Secondary Bootloader

henninjw1 — Mon, 22 Aug 2022 18:59:08 GMT

Hello,

I am having issues following AN13497. I am trying to load the bootloader onto the LPC55s36-EVK however the code provided at AN13497SW\boards\lpcxpresso55s36\dual_sbl\lpc55xx_dsbl appears to not be a complete project that I can open/build/flash in MCUXpresso ide. Is the intent to be able to open this project in MCUXpresso ide as I can with following AN12327 for the LPC55s69? What is the best way to build and flash the bootloader given the code provided in AN13497? Thanks

BTW @henninjw1 ,

Looking at the SBL example included with AN13497, I see the provided example is for ARM's MDK IDE (formerly Keil). The ZIP does not include a project for MCUXpresso IDE. Perhaps the support engineers here will have more guidance on how to use this example with MCUXpresso IDE.

Best regards

Hi,

I have asked the author of an13497, currently there is only Keil version for the software package as Derek said. Sorry for the inconvenience.

HI , I know this has been already discussed, but this is related. I am using the LPC5536 and I did my own bootloader and application. I have problems to jump to the application. I used the jump to application function from AN13497. Also, the User application startup file for the header is difficult to modify using MCU Expresso. Can you help me on how to set the application header suing MCU expresso?
