Occasional ContributorAccess config flash on Stratix 10 DX development kit
The Stratix 10 DX development kit has a QSPI configuration flash. Unfortunately, this flash chip is not connected to the Stratix 10 FPGA, it sits behind a MAX 10 FPGA that presumably runs the PFL IP...

Regular ContributorHi Alex,
Please note that QSPI is connected to the MAX 10 device only, hence you cannot configure it directly from S10 device.
Please refer Figure 29 of the user guide:
It seems that SW33.2 can help configure the flash using PCIe.
Let us know if you are able to proceed with this.
Regards.

Occasional ContributorIt's unclear what that switch does. Presumably it has something to do with the JTAG pins on the PCIe edge connector? It's unclear if those pins can really be used for anything on most motherboards. What I need to be able to do is access the flash chip somehow from the Stratix 10 FPGA, in this case this would be from a userspace application that interfaces with the Stratix 10 via the normal PCIe link.
