Issue with flashing LPCXpresso54628 EVK board.

a_s — Tue, 11 Feb 2025 13:28:42 GMT

Hello, I am trying to flash the controller via UART port using FLASH MAGIC on LPC54628 evk. Below fig. shows the configuration for flash magic:

During first flashing attempt, I accidently erased the whole chip by checking the erase entire device option in flash magic. After this, the device is not getting either in Flash magic or in MCUxpresso IDE. Looks like erasing the entire chip has erased the bootloader as well.

I am getting following error in MCUxpresso IDE:

Error: 0 available SWD Devices detected.

In what way I can recover the MCU from this stage ?

Thank You

Do you have an LPC-Link2 board available? That may get you into the chip via the JTAG/SWD port.

If not, might be a worthwhile investment.

Good luck.

Thank your for the reply.

At the moment, we are getting it in couple of days. Could you pin point the root cause of this problem ? How did the boot ROM got erased ?

Thank you for your assistance.

I don't suspect the ROM was erased (ROM = Read Only Memory) but rather the on-board debug probe got corrupted. I am not an expert in this area but it's my best guess.

Hopefully you will make some progress.

Remember to follow the procedure for using the external probe in the user manual.

I recall the following scenario:

I successfully flashed the GPIO example code from using without any issues.

When I attempted to flash the same .bin file using the Flash Magic Tool, I followed the user manual instructions. I placed the device in UART ISP mode and executed the ISP commands via a serial terminal, receiving the expected responses. I then used the following configurations in Flash Magic:

After performing these steps, the device is no longer detected by either Flash Magic or .
I am getting following error in :

Error: 0 available SWD Devices detected.

In what way I can recover the MCU from this stage ?

Hello @a_s

Have you programmed a GPIO demo without making any changes?

Please put the device back into ISP mode. Then, attempt to perform a full erase using Flash Magic. After that, try debugging again with MCUXpresso IDE. Note that you should switch to a new workspace in MCUXpresso IDE and import a new GPIO demo.

If it still doesn't work, please update the debugger firmware.

Hello @Alice_Yang ,
We initially programmed the demo GPIO, and the execution was successful. We also configured the device in ISP mode and attempted to erase the Flash using Flash Magic. However, we encountered the following error:

Despite trying all the supported baud rates in Flash Magic, the error persists.

Could you kindly guide us on how to proceed with updating the debugger firmware?

Thank you for your assistance, and I look forward to your prompt response.

Best regards,
Akshay

Hello @Alice_Yang,

I have gone through the link which you have attached, but page is not available:

Then I have referred User Manual, the mentioned link is also not available :
http://www.nxp.com/lpcutilities

Is there any other source for the document?

Kindly help on this ASAP as we are unable to use the evaluation board.

Best Regards,

Akshay
