Hi Sir,

I used the J-link SWD interface to connect to our board and successfully read the SWD device ID.

But Read Back Entire Chip will have the following error message,Erase also has the same error message.

Our hardware circuit is as follows

Please help to confirm if the hardware need to be modified.

Thank you

Regards,
Gary

Hi Gary Yang,

Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
After having a brief review of the schematic, I don't find something wrong with it, so whether you can introduce the complete steps to replicate the phenomenon.
Have a great day,
TIC

Hi Sir,

My tested steps are as follows

step1. Select device NXP LPC54608J512

step2. Target-->Connect, successfully read the SWD ID

step3. Target-->Manual Programming-->Read Back-->Entire chip

Repeat step1 and step2
step4. Target-->Manual Programming-->Erase Chip

Please help with suggestions

Thank you

Regards,
Gary

Are you sure that you have a flash connected to the interface which addresses 0x10000000?

This is the memory area of the QSPI flash, connected to the SPIFI.

And the second point is: does J-Flash know how to deal with this QSPI flash? Is there maybe something to set in the Flash tab of the project settings?

Regards,

Bernhard.

Hi Gary Yang,

Thanks for your reply.
I'd like to follow the steps to replicate the phenomenon, however, on my site, it works well actually.
