Failed to upgrade my application on LPC55S69 EVK in ISP mode

[sushmasan]

Hello Team,

I am seeing an issue while upgrading the firmware on LPC55s69 evk using flash magic tool.

During verification I am seeing a failure.

Please find the attached snapshots as a reference,

Can someone please let me know, what is going on?

Some additional information,

I even tried flashing using blhost tool, I did a write the firmware to flash and I read from flash that works fine, but after reset I don't see any difference.

Just FYI, I tried flashing "led_blinky" release .hex firmware on to the LPC55S69 EVK.

Regards,
San

Hello @Alice_Yang ,

I didn't realize I am using an older version of Flash Magic tool. But after upgrading flash magic to a newer version, the firmware upgrade was successful. There are no changes to made to my code apart from installing a new version of flash magic tool.

I even tried with MCUXpresso IDE, now I was able to do the firmware upgrade.

But still there is another issue. I am able to do firmware only the debug version of the firmware, not the release configuration image. Any idea, what might cause that issue?

Regards,
San

Hello @sushmasan 

How did you generate the release version? What errors occurred? Could you please provide a screenshot of the error?

Hello @Alice_Yang ,

I have generated .hex using the Binutils on the IDE. Looks like only this particular hex file has failed. Where as I have created a new project and built it. Now I am able to upgrade both debug and release configuration images on the LPC55S69 EVK.

Thanks.

Hello @sushmasan 

Please convert your led_blinky.hex  to a .bin file.

And  please erase the flash before writing.
