Custom board with XUF216-512-TQ128-C20A - xrun works, xflash doesn't

[dtns]

If I run the firmware via xrun, it is working successfully.

If I am trying to flash the integrated flash, it fails.

Site 0 has started.
Site 0 has ID 0x9d6015.
Site 0 erase 0x00000000.
Site 0 write 0x00000000.
Verify failed for page 0x00000000, offset 0x0000 (read 0x00, expected 0x37).

This happens on both test boards.

XFLASH version ? External pullup for internal flash placed ?

[Joe]

Site 0 has ID 0x9d6015

This means the xcore has read the device ID from the flash correctly. This read is via serial SPI. It's possible the QE bit in the flash has not been set which would stop the Quad read working in the verify stage. I would check the XN to see the qe bit location is defined correctly and/or check the build in general is for the correct device etc.

xflash version: Build 61-0e6d8350, Jul-04-2024
Pullup on X0D01 is present (1k).

Sorry for the stupid question, but how to I set the QE bit? This is my first custom XMOS board bringup.
Before that, I was using a board from DIYINHK with the same XUF216 and things were working with the same target definition (and the board was also using a XUF216-512-TQ128.

I've just spotted another error. The Package was defined XS2-UnA-512-FB236 (but worked), but apparently should be set to XS2-UFnA-512-TQ128 (note the F).
Will check if this resolves the issue as soon as I am back in the office.

Edit: Unfortunately this didn't fix it.

Did you see the recent answers in this thread? https://www.xcore.com/viewtopic.php?t=8830

It goes into details regarding the QE bit.

Still same problem

Weirdly enough the flash read reads 0x00 from the register even after the xflash write command.

Areyou sure your IC is XUF and not XU ? When yes show your schematics

[Joe]

I don't think those flash commands are doing what you think they are.

Try some basics:
xflash --spi-read-id 0x9F
Should repeat the device Id read by the tools 0x9d6015.

xflash --spi-command 0x5A 256 0x00 0x00 0x00
Shold read the entire SFDP structure.

Maybe start by using the XN built into the tools.
