Hello,
We've been contracted to port an old RTOS to a system running on the Intel Elkhart Lake X6000E
after solving UEFI related issues, I am now working on networking support. I've decided to import a driver from OpenBSD, the synopsis GMAC driver which is easier to port than the Linux stmmac driver.
I've downloaded the following documentation: vol1: 636112, vol2: 636722,635255,636723
636722 - chapter 10 contains a list of registers, that I am able to read/write to. So far it has been helpful to setup the device. However when I read DMA_DEBUG_STATUS0 it says Rx Descriptor error...
vol1 - chapter 15, describes features, interrupts.
However, I can not seem to find any information on the Rx/Tx descriptors, and their RDES/TDES fields.
I can go by the source code and documentation from other vendors I found on google, but this is work and not a reverse engineering challenge
Any help will be greatly appreciated.
- Erik
