Tried to load assembly that has been already loaded, LiteX_I2C_Zephyr.cs

[mofanv]

Hi,

When I start with renode litex-vexriscv-tflite.resc, it shows with the error

(monitor) s @litex-vexriscv-tflite.resc
No such file Users/litex-vexriscv-tensorflow-lite-demo/renode/LiteX_I2C_Zephyr.cs.
(monitor) 

. I checked that there is no such file even in github repo. So I guess it is generated during building or compiling? Can I ask where to find this file?

• Renode, version 1.13.0.16683 (e7f96b97-202204300916)
• System: Mac Mini with M1. I installed Zephyr SDK 0.14 following their webpage, without running zephyr-sdk-0.11.2-setup.run file. There is no 0.14 under toolschain/zephyr folder, so I just copied and paste 0.11 as 0.14. Is this the cause of such no file.

Thank you!

Update:

After I copy-pasted https://github.com/renode/renode-infrastructure/blob/master/src/Emulator/Peripherals/Peripherals/I2C/LiteX_I2C_Zephyr.cs into the folder and run, now the error is:

(monitor) i $CWD/litex-vexriscv-tflite.resc
Errors during compilation or loading:
Tried to load assembly that has been already loaded. Aborting operation.

Hi @mofanv, thanks for reporting the issue.

This file was intiialy hosted in this repository and later moved to Renode itself.
3f1dac4 should fix the problem.

Thanks @mateusz-holenko .

Above error disappeared, but seems there is another problem. At the machine--0:sysbus.uart, there is only one line, nothing else.

*** Booting Zephyr OS build 0.6.0-98949-gfc8918faa9fa  ***

I guess it is due to that in the host terminal, it shows a non existing peripheral.

Can you please kindly point out is this also a problem caused by the LiteX_I2C_Zephyr.cs file? or another file.
