DV 08:47 PM PCB Development: RE: RGMII Voltage Levels

Hi Lucas,
You are correct the RGMII interface on the SOM is hardset to 1.8V, which wouldn't be able to interface with a 3.3V PHY. In order to interface to a 3.3V level ethernet PHY you need to route one of the HPS ethernet MACs throug... Daniel Vincelette

LU 04:17 PM PCB Development: RGMII Voltage Levels

I'm trying to determine if a alternate Ethernet PHY is okay to use with the RGMII interface of the SOM module. PHY controllers such as the LAN8670 and KSZ8041 tout their single 3.3v supply, so I'm assuming that's the voltage level they u... Lucas Uecker

Good to hear; you're welcome! Zachary Miller

Hi
That works with *socfpga.dtsi* from 5.15.30-lts (and no *skeleton.dtsi* required).
I can now erase, write and read the QSPI NOR Flash.
Thanks a lot.

Hi Matthew,
Give it a try with the @socfpga.dtsi@ from Altera's @socfpga-5.15.30-lts@ branch instead (you won't need @skeleton.dtsi@ anymore either). The compatible string for the QSPI controller changed, but the driver _also_ still a... Zachary Miller

Hi,
Thanks Zachary,
Yes CONFIG_MTD_SPI_NOR is set to [y] (as is ARCH_INTEL_SOCFPGA, which initially caught me out as it's was no longer ARCH_SOCFPGA).
I've attached a zip file containing our 5.15.30-lts kernel config and the device ... Mathew Jones

ZM 07:27 PM Software Development: RE: MitySOM-5CSX-H6-4YA Linux kernel 5.15 QSPI NOR Flash access

Hi Matthew,
It looks like @CONFIG_MTD_M25P80@ has been superseded by @CONFIG_MTD_SPI_NOR@, which should already be enabled in the stock 5CSx defconfig from our @socfpga-4.9.78-ltsi@ branch.
Could you post your kernel config and dev... Zachary Miller

Hi,
We’re using the MitySOM-5CSX-H6-4YA and previously we used the Linux kernel 3.16.0 as supplied by CriticalLink, but this time we need to use a more recent kernel (5.13 or later).
I've taken the kernel 5.15.30-lts source from "Alter... Mathew Jones
