New project, litehm2: a hostmot2 port to linsn rv901t

I managed to reduce the footprint of the design and pushed an update.
It needs two patches to litex/liteeth:

github.com/sensille/litex/tree/tx_write_only and
github.com/sensille/liteeth/tree/tx_write_only

I also reduced the system clock from 100 to 80MHz, which should still be plenty. Before, it sometimes slightly missed timing closure, now it is solid.

Brush into rv901t_stock__example_in_initial.bin and ping10.10.10.10 can pass
Then mesaflash --addr 10.10.10.10 --device ether --write rv901t_stock__example_in_initial.bit --fix-boot-block

what do I need to do? Transform rv901t or install any software driver？
 

The supplied linuxcnc was only meant as an example. Initially it matched rv901t_4out__3stepgen_2enc_1pwm.conf, but I have modified the litehm2-config slightly since, without updating the 6040 config.
But "mb2hal parse_main_args ERR: wrong number of args" sounds more like a problem with linuxcnc.
Did you build it yourself from linuxcnc/master? mb2hal also has changed a bit since I made the config. It would be best to start with the smallest possible config, or even with halrun first.

My linuxcnc is downloaded from the build robot linuxcnc-uspace_2.10.0~pre0.1542.g93fccc095_amd64.deb 2023-06-19 21:34
You said there would be a patch merged into 2.10
The file rv901t_stock__with_jp4_initial.bin is programmed and uploaded to linsn rv901t can’t be pinged with 10.10.10.10, but the other two firmwares can


 

sensille 帖子=274442 用户id=33477提供的 linuxcnc 仅作为示例。最初它与 rv901t_4out__3stepgen_2enc_1pwm.conf 匹配，但此后我稍微修改了 litehm2-config，而没有更新 6040 配置。
但是“mb2hal parse_main_args ERR：错误的参数数量”听起来更像是 linuxcnc 的问题。
你是从 linuxcnc/master 自己构建的吗？自从我进行配置以来，mb2hal 也发生了一些变化。最好从尽可能小的配置开始，甚至先从 halrun 开始。

The error you pasted was about mb2hal, not litehm2. You probably don't need mb2hal. Try to write a very small config.

Thank sensille
Comment out all the output and finally be able to start linuxcnc
Maybe I should modify the circuit of rv901t before running linuxcnc


 

rv901t_4out__3stepgen_2enc_1pwm, can you do a pre-firmware bit that will contain 6 outputs, 20 inputs, 6 stepgens, 6 encoder interfaces and 2 pwm generators.

Yes. Did you modify the board in the same way I did?
Do you want differential stepgen?

Thank sensille
Yes, I want differential stepgen, because it can better support servo motors,
I would like to try Ilya Koubatkin's retrofit method first and am also interested in your method
