- AF 09:33 PM Software Development: RE: Using GPIO command on UBoot command line...is there any pin mapping between HPS pin # and GPIO pin #?
- From Dan at CL (Thanks Dan!)
Our reference project has the following HPS IO set as GPIO:
- GPIO40 — edge pin 264 — SDMMC_D4/USB0_D4/HPS_GPIO40
- GPIO41 — edge pin 266 — SDMMC_D5/USB0_D5/HPS_GPIO41
- GPIO48 — edge pin 38 — TRACE_C...

- Hi,
I have the CriticalLink UBoot image on a terminal program. There is the GPIO set/clear/toggle command. It wants a pin number. I have a logic analyzer on HPS GPIO 53 (pin 26 on the MitySOM connector). After UBoot comes up, that...

- Hi Mike,
Thank you for the confirmation. I've attached a picture of my proposed update to our MitySOM boards. Any comments appreciated.
Best Regards,

- Hi Austin,
You are correct that the Cyclone V cannot drive this pin. It is a configuration control input which must be driven externally via HW if needed. You would drive this pin low if you needed to reset, reconfigure the device or ...

- On the CriticalLink MitySOM-5CSX development board, there is an LED D100 connected to nCONFIG (pin 39). According to the Intel/Altera documentation, nCONFIG is an input to the Cyclone V. I don't find anything in the Intel/Altera docs t...
