Black Magic Probe - LPC43xx

Anyone knows if its possible to flash SPIFI on a LPC4320 using a black magic probe?

I have a hackrf-one board with dead USB port (only power, unknown reason), and I'm trying to download an updated firmware using JTAG. I can use JTAG to read/dump the firmware, inspect ram and debug, but I found no ways to download the firmware to flash.

Any thougts?

Hi, Fernando,

I have searched the "black magic probe" device, it is from ST company, and is used to download/debug for STM32 family, but i am not familiar with the device.

If you can use it to download/debug the LPC4320, I think it is okay.

As you know that the LPC4320 does not have on-chip flash, I suppose that you use external spifi flash and you want to download code to external spifi flash. Can you tell us the tools and the P/N of the external spifi flasg you are using to download to external spifi flash? if you use MCUXpresso tools, pls refer to section 15.2.2 LPC SPIFI QSPI Flash Drivers in MCUXpresso_IDE_User_guide.pdf, located at:

C:\nxp\MCUXpressoIDE_11.1.1_3241

I copy the part here:
