Hello everyone:
I am testing S32G274ARDB2 board, I have trouble in testing switch of SJA1110.My test environment is default Yocto BSP.
In UG:
The Linux kernel module is automatically inserted at boot time on S32G274A RDB2. In order for the driver to
update the firmware of the switch and/or the uC, please provide the path to the binaries on the host machine in
conf/local.conf before the yocto build.
SJA1110_SWITCH_FW = <path_to_sja_switch_binaries>
SJA1110_UC_FW = <path_to_sja_uc_binaries>
Where path_to_sja_switch_binaries is .../sja1110_switch.bin and path_to_sja_uc_binaries is
.../sja1110_uc.bin.
But I can not find sja1110_switch.bin and sja1110_uc.bin. So I download GoldVIP-1.4.0-binaries.zip, and find these two files, then I build Yocto BSP agin. I set SW12 on 1-1 position, but can not work.
You can see below:
Who can help me, thank you.

Hello Daniel,
Thank you for your reply. I think I've solved my problem.
From the picture of first floor, I think the sja1110 does not operation properly, but my pc can conmunication with pfe0, the sja1110 actually works. so I want to know what's problem with sja1110, and update the FW of sja1110.
So I think there may be some fault in first method.
Hi,
The bootmode for SJA1110A on the RDB2 is set to use the SPI Flash connected to it. SJA1110A has already FW flashed to the SPI NOR Flash in this board.
Have you tried using the SJA with the FW provided with the board? Do you have problems reaching to it with the default FW??
