SJA1105R firmware and configuration

[hkaranji]

Hi,

I am using SJA1105R automotive switch.

I am using the driver provided here sja1105x_linux_switchdev - SJA1105x Ethernet switches Linux Driver 

I generated the firmware hex file (examplePQRS_SJA1105PR.hex) and C file (examplePQRS_SJA1105PR.c) using examplePQRS.py in sw425110 Configuration-generation-tool.

I want to know how to use above files?

The generated C file has function SJA1105P_loadConfig.

However in file sja1105x_linux_switchdev/platform_independent/src/NXP_SJA1105P_configStream.c the function SJA1105P_loadConfig is already there.

Do I need to replace NXP_SJA1105P_configStream.c with examplePQRS_SJA1105PR.c?

The device tree specifies a firmware name. So I have specified examplePQRS_SJA1105PR.hex as firmware name and copied this file into /lib/firmware.

My question is if we are generating a C file using same hex file do we really need the firmware file at all?

Overall I am confused about the usage of the firmware hex file and c file.

Appreciate any kind of help.

Thanks,

Hrishikesh

Hi,

Thanks a lot for your reply.

Which is the latest code base I should be using for this?

If you are working with a package that incorporates the switch driver,
e.g. NXP automotive BSP, stay with the most recent BSP. If you are
maintaining your custom kernel, stay with this repository, master branch:

https://source.codeaurora.org/external/autoivnsw/sja1105x_linux_switchdev/

Have a great day,

Hi,

Thanks a lot.

We are already using same repository.

Thanks,

My apologies for the late update, you don't have to alter the driver
source code to modify the static configuration, although in theory you can.
The recommended way to provide a static switch configuration to the Linux driver is by means of a
firmware binary file. The driver should build the default one for
you. The location of the file is specified in the Device Tree.
The firmware file format is binary, not hex, so if you created
your static configuration externally, use intelhex.py to convert from
hex to bin. See this for an invocation example.

Have a great day,
Platon

Hi,

I used this utility to make firmware bin and tried to load.

I am getting following error,
