cvwsoc: First Renode co-simulation setup. - #22
Merged
Conversation
It allows to co-simulate Renodes Hifive FU540 SoC with CVWSoC AXI setup. Many limitations still exist: - AXI bus at 2 MHz for simulation performance reasons - 200M Ethernet clock, 22.xx MHz audio clock and 48 MHz USB clock are not simulated for co-simulation performance reasons - All Renode CPUs but one had to be disabled because otherwise simulation hangs completely (????) - Many issues when passing/using -e settings to Renode. Full paths are generated from the caller Makefile. Features: - MMIO access to all peripherals - For audio testing the real audio clock must be enabled (slow) - SD card model with test SD card image connected to SDHCI peripheral - iDMA tested without issues (slow) - Ethernet starts up on boot (not really usable) - USB initialized on boot (not really usable) - VGA not tested. Needs either u-boot or Linux initialization. It will probably slow down simulation quite a bit. The 'cosim-run' target needs a 'fw_payload.elf' with Kernel (with initramfs) payload. This is built in the specific Yocto (KAS) target. Signed-off-by: Juan Schroeder <jcschroeder@gmail.com>
