Problems with programing NGX LPC4330-Xplorer board via jtag

Hello,

For two days I am trying to flash firmware to LPC4330 with spifi external flash. I have tried every tool (Keil uVision, IAR, RedSuite, LPCExpress, openocd) and all JTAG's (FT2232(BusBlaster), LPC-Link, Keil ulink) but no luck to program it.

THe problem is that after uploading firmware via jtag and verifying everything is ok until next reset. After the reset the flash the same as it was before (the contents of flash is firmware which was shipped with the boards)  I have tried two boards but have no luck with modifying external flash...

I can't continue development as I can't upload Hello World example to the board :(

Kind Regards,
Aurimas

IIRC you'll need to ensure that there is no valid image in the internal flash (do a mass erase) before the LPC4337 will boot from external flash.

Oh thank god... Yes it's mismatched silicon :( Will it work with external flash?

In that case, check the boot pin settings on your board.

The other thing to double check is what silicon is actually fitted to your board. I believe that recent batches of the NGX Xplorer boards have been fitted with LPC4337 MCUs (ie with internal flash) rather than the flashless LPC4330.

Hello,

Yes, I have tried those examples selected to flash to the SPIFI but no changes... I even hooked up logic analyser and sniffed quad spi flash chip... The commands are sent and everything should be working but not. In evening I will try to look up on flash chip with programmer and check maybe it's damaged or somehow locked.

Best,
Aurimas

First of all note that LPCXpresso 5.2.6 ships with a few examples for the NGX Xplorer-4330 which are set up to download and run from SPIFI flash. Have you tried using those?

From the limited information you have provided, it sounds to me like your are programming your application into RAM, not into the flash.

For LPCXpresso / LPC-Link usage, I suggest you take a look at:

If you need more help, post your AXF, linker map file and the debug log from starting a debug session...
