I am working on a dual-core application targeting the LPCXpresso 54102 evaluation board. After recently making some simple changes to the C code, I am no longer able to flash the device. I get this message:

I don't know why it no longer working. Any help would be appreciated. I have attached my projects in a single ZIP file.

Does your application configure for low power, or use a sleep mode? If so, boot the part into the ISP before you start your debug session. In fact, do it anyway.

Regaining debug access to target MCU

Thanks and regards,

No, the application does not configure for low power or use sleep mode.

I have followed the linked-to instructions, but I still get the same error message when attempting to flash an image.

Also, I realize that flashing the board and starting a debug session is a similar process; but just to be clear, I have no trouble starting a debug session. (And in case this matters in terms of replicating the problem, note that the image I am attempting to flash is compiled in a "release" configuration.)

And in case you're wondering, I can't just use a debug session, unfortunately. The code running on the M0+ is very time sensitive, but the overhead of a debug session on the M0+ is significant. (The M4 is fine. I assume the M4 has support for hardware breakpoints and the like while the M0+ doesn't?)

One more thing. I have two boards, and I see the same issue with both of them.

I can't reproduce your problem here using the project that you supplied.

Looking at your original log (from using the GUI flash programmer I presume?) the curious thing is the lines:

Nt: Loading ELF file 'spectrum-analyzer-m4-master.axf' at location 020108E4
Nt: Writing 4 bytes to address 0x020108E4 in Flash
Ed:05: File 'spectrum-analyzer-m4-master.axf' load failure: Eg(10). Attempt to load into missing flash area.

the address of which is in RAM, and hence shouldn't be being programmed as flash anyway!

Can you ZIP up and provide the actual AXF file that you are trying to flash?

And also provide the actual command line displayed at the top of the GUI flash programmer after it runs.

Yes, that's from using the "Program Flash" button in the LPCXpresso (version 7.8.0, build 426) tool bar. (I'm sorry, I should have mentioned that earlier.)

Here's the command line:

Quote:
crt_emu_cm_redlink -flash-load-exec "C: xp\workspace\54102\spectrum-analyzer-m4-master\Release\spectrum-analyzer-m4-
master.axf" -g -2 -vendor=NXP -pLPC54102J512 -reset=vectreset -flash-driver=LPC5410x_512K.cfx

And I have attached my AXF file.

Please can you try building and downloading your image using LPCXpresso IDE v7.9.2.

I believe your issue is related to one of the multicore project related fixes that we made in LPCXpresso IDE v7.9.0 : https://www.lpcware.com/content/forum/lpcxpresso-latest-release

You can safely install LPCXpresso v7.9.2 without uninstalling your current version. And then for testing purposes, you might want to create a new workspace and import your existing projects into it.
