Drivers/specifications for baremetal programming #179

Closed AnoudAlshnakat closed 3 years ago

AnoudAlshnakat commented 3 years ago

Hey.

My colleague and I are working with the Genesys II Kintex-7 board, with the lowRISC ariane v0.7 SoC.

We are porting a minimal separation kernel and we are writing baremetal code for lowRISC. Our code must control the following devices: UART, clock/timer, and Ethernet.​

We cannot find the specifications (programming interfaces) of the UART, timer/clock and the Ethernet devices. Can you please point us to the device specifications or to the Linux drivers controlling these devices?​ Can you please point us to the device specifications or to the Linux drivers controlling these devices?

It’s true there isn’t much documentation of devices outside of the Verilog RTL code, however you should find a comprehensive set of drivers inside Linux-5.3.18.patch at the toplevel of the repo.
