DSA and SPI issues

xiaoshumiao — Thu, 22 May 2025 02:03:10 GMT

Hi:

I am using S32G-VNP-RDB3 and Linux BSP 43.0

Before I enabled sja1110 DSA, I could flash the firmware via spi and JTAG according to 'S32G-VNP-RDB3 Ethernet Enablement Guide', and could ping 192.168.0.200 successfully in linux.

When I enabled DSA, executing the command setenv sja1110_dsa yes in uboot, and set J189 Pin1-2: Short, Pin3-4: Short, I found that I could not load the sja1110 firmware through spi.

I set J189 (Pin1-2: Open; Pin3-4: Short) and wrote firmware via JTAG port successfully. then I set J189 (Pin1-2: Short; Pin3-4: Short) to use dsa , ping 192.168.0.200 failed.

My question ： how to flash sja1110 firmware when using DSA.

Hello, @xiaoshumiao

Thanks for the post.

Once using DSA driver for SJA1110, the firmware you mentioned is not needed for use the ports of SJA1110.

since firmware running inside SJA1110, the ping operation failed.

Hello, @xiaoshumiao

Thanks for your reply.

For such cases, every ports of SJA1110 could be directly shown in Linux(could be seen from ifconfig -a or other commands), you may set IP for the port that wish to use, and directly use it then.
