| somlo | mithro: in litex | 00:21 |
|---|---|---|
| mithro | lm32 has been used more for bare metal | 00:21 |
| mithro | mor1kx has been used more for Linux | 00:21 |
| somlo | mithro: I just need to test some register read/write functions on both little and big endian, so I think for a proof of concept bare metal is enough... I'll go with the first one for which I find an easy to download and install toolchain... :) | 00:26 |
| mithro | somlo: Well, we have toolchains for both in litex-buildenv / conda / etc | 00:33 |
| somlo | mithro: cool, thanks! so it is down to flipping a coin, then :) | 00:39 |

| scanakci | https://usercontent.irccloud-cdn.com/file/9ER4SuPZ/BIOS_help.png | 07:56 |
| scanakci | finally realized the issue. help command works fine. crcbios() causes trap in BP, which requires some debugging | 07:58 |
| scanakci | _florent: I would like to run a program that I load into main memory (to show that we can use LITEDRAM). In simulation, how can I load the program?. You mentioned that --with-sdram should be my next step after BIOS. What exactly does it do? | 08:02 |
| scanakci | _florent_: | 08:02 |

| mithro | scanakci: somlo might be able to help -- he was working on Rocket support in LiteX which is also a 64bit RISC-V | 08:47 |
| _florent_ | scanakci: --with-sdram add LiteDRAM + a SDRAM to the SOC (using a DFI SDRAM model) | 08:53 |
| _florent_ | scanakci: this will also enable the memtest in the bios | 08:54 |
| _florent_ | so you can test that to verify that LiteDRAM is working correctly with your SoC | 08:54 |
| _florent_ | you can then use mr/mw command to do some tests on the SDRAM (should be at 0x4000000 if you still have the same mem_map) | 08:55 |
| _florent_ | afterthat, if you want to load and run software from the SDRAM, you can use the TFTP: --with-sdram --with-ethernet | 08:56 |
| _florent_ | this will try to get a boot.bin file on 192.168.1.50 and then run it | 08:56 |
| _florent_ | you can find a simple firmware example here: https://github.com/enjoy-digital/chubby75/tree/master/firmware | 08:57 |
