Our custom hardware makes it difficult to use your HDL exactly as is. We have some extra functional needs, like an I2C, a second SPI, a pulse generator, etc, that have been customized, and some extra features like HDMI, etc, that have been eliminated. That said, if I need to make changes, I can. Can you explain what areas of the HDL would affect the charge pump calibration?
I did re-pull the SW from github and rebuild it. I had to change a couple of extra things, like the SPI core we use is on channel 1, not channel 0, and for some reason your SPI init and read routines don't work on our hardware, so I had to make some modifications to get those going. The software still freezes at the same spot though, even after a manual power down and reload of the bit file and firmware.
We are going to add a physical wire to the RESETB pin so we can do a manual reset at the appropriate point in the code, but in the meantime, can you think of anything else that would affect the charge pump calibration? Other calibration routines further down the code work fine if I comment out the charge pump calibration. Thanks.
