BTW, here is a patch that you might want to apply to qemu if you intend to run RTEMS on leon3. The plug area must support byte accesses, which is used by the RTEMS grlib scanning functions... Jiri. On 10/23/19 8:37 PM, Jiri Gaisler wrote: > Leon3 uses the GRETH ethernet IP core for network

Leon3 uses the GRETH ethernet IP core for networking. You would need to write a qemu emulation model of it to get networking support. The GRETH is fairly well described in the GRLIB IP manual, so it should not be impossible. The core is also available in open-source (VHDL) if you need to look up

I am a bit against the merge of AHB and APB initialization into the same function. A grlib system can have any number of AHB and APB buses, so there really should be a separate init routine per bus as in the original patch. Jiri. On 10/09/2014 01:05 PM, Fabien Chouteau wrote: From: Jiri
