XC7A200 on TE0712: Boot from flash only after one time programming with Xilinx tools

[UweBonnes]

I got new TE0712 modules. On a working setup, I replaced an old programmed modules with the new module. I could load the bitfile to FPGA, and the board worked as expected until reboot/repower. Then I wrote the binfile to flash. It compared okay. But the module, more exactly both modules i bought, did not boot from flash, neither by reset or repower.

To get the module bootable, I needed to use the Xilinix programmer once to program the flash. After the one-time xilinx programming, I can erase and reprogram flash and the setup boots from flash as expected.

Any ideas what openFPGAloader is missing on a virgin setup of FPGA/Flash to get flash bootable?

Is your bitstream is configured in quad spi mode? If so, maybe the SPI flash has quad mode disabled?
I have observed this situation after a wrong status register write where the quad enable bit was unset.

Any news? Thanks

Sorry, I am missing knowledge to answer you question. Are these settings related?
1:set_property BITSTREAM.GENERAL.COMPRESS TRUE [current_design]
2:set_property BITSTREAM.CONFIG.CONFIGRATE 66 [current_design]
6:set_property BITSTREAM.CONFIG.SPI_32BIT_ADDR YES [current_design]
7:set_property BITSTREAM.CONFIG.SPI_BUSWIDTH 4 [current_design]
8:set_property BITSTREAM.CONFIG.UNUSEDPIN PULLDOWN [current_design]

Sorry for the delay.
According to the configuration the bitstream is read in quad mode. So if the flash chip is not configured to support this mode, loading the file will fails.
Could you check your flash configuration (openFPGALoader may do that with -f --detect.

This is the flash after one time Xilinx programming and then multiple times openFPGALoader programming:> ~/devel/openFPGALoader/build/openFPGALoader -b te0712_8 -f --detect

"QUAD :1" seems to be loaded. Can openFPGALoader set it? A grep through the code did not ring a bell for me.

[trabucayre]

Currently the only modification applied by openFPGALoader is about protection. Enabling/disabling quad mode isn't supported (but it's possible to integrate this option).
