Regarding flash erase of LPC4330
Hi,
I am having LPC4330 Xpresso board and LPC link2.
Don't know what I had done but now I am not able to download any code into flash.
And I am not able to erase the flash too.
I tried boot ISP, vector catch methods discussed in this forum but no help.
This is the message I get when I try to load program. Please help.
I tried with other flash drivers: LPC18_43_GENERIC.cfx and LPC18_43_SPIFI_16MB_64KB but same result.
I am trying one of LPCOpen examples for download. It worked before. I tried one of my own program and after that this happened. Now I am not able to load LPCOpen examples also.
If I don't enable vector catch, it reports erase successfully but I see that contents are still present in flash (resetting executes previous program).
Flash erase log:

If the suggestion from Carlos is unsuccessful, it would be useful to identify the actual SPIFI device fitted to this board. This can be read directly from the top of the 8 pin device located on the bottom right of the board (with the USB connectors to the left) or identified via LPCScrypt via the command 'querySPIFI.

I tried boot ISP, vector catch methods but did not help.
There is already a blinky program in flash and that program I could run and debug.
I could not change anything in that flash now. Could not erase the flash or download new program.
Only blinky successfully downloads again (may be because writes are ignored and read comparison is successful).
Rgds,
Venkat.

Hi Venkat,
Has your application code by any chance locked any of the sectors in the external SPIFI flash? You may be able to use LPCScrypt to erase whatever you have programmed into the SPIFI flash that has put the board into its current state.
Hope it helps!
