Reprogramming LPC3154 at LPCxpresso

I wonder, if that's possible to load lpc3154 at LPCExpresso board with custom firmware? I see that chip supports secure boot, so if AES key was programmed, it is impossible without knowing the key? Or are there any options to boot lpc3154 without…

How to automatically allocate a page of flash for in-application storage of settings

I've been using the LPC8xx range of Cortex-M0+ MCUs quite successfully. One difficiency: these don't have inbuilt EEPROM (to preserve settings across power cycles etc). However there is a work-around: using the in-application flash programmer, a…

LPCxpresso: How to write a constant value to flash memory at programming time?

Is there a file or setting that I can add to my project that maps specific values to specific memory location in IAP flash when it is programmed? The device is LPC1114. The use case is that each device needs a unique serial number that should be set…

Flashing LPC1769 with FlashMagic

I'm encountering problems flashing my LPCxpresso1769 with FlashMagic. I had previously been able to get it to work using a USB to UART lead (TTL-234X-3V3) and powering the device externally (i.e. not via the USB debug probe). I've since lost the…
