I had a working J-Flash project for a custom board similar to STM32F746 DISCO.
The QSPI flash on the board is S25FL256L, J-Flash could program it and read back.
Today updated to version 7.82c, Windows 64-bit, on Win11.
When I opened the project it complained that the loader for ext . flash is wrong
and demanded to change it to "CLK@PB2_nCS@PB6_D0@PD11_D1@PD12_D2@PE2_D3@PD13"
After that it no longer can read the QSPI flash. Says:
It also advised to update the J-Link firmware. I did it, it does not help.
My QSPI pinout is indeed CLK@PB2_nCS@PB6_D0@PD11_D1@PD12_D2@PE2_D3@PD13.
Also tried the alternate pinout CLK@PB2_nCS@PB6_D0@PC9_D1@PC10_D2@PE2_D3@PD13
Does not help either.
I know that this is not a support forum, just to warn the users that new J-Link versions are not properly tested for regressions
.
Attached the old, new (updated by new j-link version) projects.
