| vidya | Hello all, I'm trying to simulate mor1kx using Verilator and everytime it seems to download the core from github. How can I avoid it from downloading from github | 08:35 |
|---|---|---|
| vidya | This is what it says :INFO: Preparing verilator_tb_utils INFO: Preparing adv_debug_sys INFO: Preparing jtag_tap-1.13 INFO: Preparing mor1kx INFO: Downloading openrisc/mor1kx from github | 08:35 |
| SMDhome | guys, I wonder if uart_base_address should be specified during compilation or not? Should -mboard key set it? | 13:00 |
| olofk_ | SMDhome: If you're not using -mboard, I think it uses the or1ksim settings by default | 13:16 |
| olofk_ | And or1ksim is set up to print characters to stdout by putting the value in register r3 and then call l.nop 0x3 (I think) | 13:16 |
| olofk_ | So if you want the data to be sent to a real uart you need to set -mboard | 13:17 |
| olofk_ | You can probably use any board, but -mboard=de0_nano is a safe choice | 13:17 |
| SMDhome | olofk_: ok, let me test | 13:17 |
| olofk_ | Or you can create your own libboard. I've been meaning to write some instructions for that, but haven't gotten around to do it | 13:17 |
| ZipCPU | So ... those are probably the instructions you were staring at and wondering at the top of dhry_1.c. | 13:20 |
| ZipCPU | SMDhome: They provide the meaning of the symbols that libboard would've defined, in order to use a UART. | 13:20 |
| SMDhome | olofk_: setting denano board does the trick, at least i see some values set in the binary. But running such binary on verilated sim hangs for some reason. | 13:23 |
| ZipCPU | SMDhome: are the values set ... the right ones for a Verilator simulation? | 13:25 |
| SMDhome | uart baud and etc seems ok, but I can't tell the same for others: i.e. memory could be mapped to another addresses and etc. I'll check difference between de board and or1ksim board files | 13:27 |
| SMDhome | memsize and uart_irq are different at least | 13:28 |
| ZipCPU | SMDhome: uart_irq is necessary for receiving on the UART port, not quite as necessary for transmitting. | 13:29 |
