LPC4357 Flash Driver Error

[px_seven]

Hello,

I am having problems flashing the LPC4357 using an LPCLink-2 debugger. The flash driver is downloaded to RAM but the driver complains about what I assume is code corruption. This is the output from the GUI flash tool console:

Sending VECTRESET to run flash driver
There was a problem after we succesfully downloaded flash driver code to the target, so we are going to compare the flash driver code with the memory where it was loaded.
Note that, after driver initialization, some difference is normal in 'generic' drivers.

Note that flash bank B is flashed OK and works, despite the reported flash driver error.

I have tried using both JTAG and SWD, two different but identical 4357 boards using 20-pin trace/JTAG/SWD connector and one other 4357 board with 10-pin JTAG/SWD connector. I have also tried old scripts from LPCExpresso 7.1.1 and 6.1.2, but they gave the same error.

I should say that I have used these exact boards and the same LPCLink-2 a number of years ago (2013-2014), and then they did not have these problems. Could it be that the LPCLink-2 is damaged?

Do you have any ideas what the problem might be?

I have located the problem, and it was due to a dual core application where the Cortex-M0 was linked to use the same RAM as the flash driver was uploaded to. The M0 then corrupted the flash driver image in RAM as it was executing while flashing process was ongoing.

I solved it by a single line of debugger code which halts the M0 on debugger connect:

10 CMHALT 1 1

I put this in a .scp script file which executes on flash and debug init.

NXP, maybe you should consider to halt the M0 in your connect procedure, as it is of no use having it execute during the flash or debug session init. I saw other people have had the same problem years ago:
