s32g sja1110 startup

[jiajun_cheng]

Hi,

I am developing the functions of SJA1110 recently, and I know very little about it. Currently, the SJA1110 S32 SDK is being applied for by the supplier. I can only learn about the functions of SJA1110 through "S32G2_LinuxBSP_39.0_User_Manual.pdf" and posts on the forum. So I have the following questions:
1. What are the functions of SJA1110 S32 SDK? Can I use this SDK to configure the port functions of SJA1110 on S32DS? Because the network interface of our customized version is slightly different from that of S32G2-VNP-RDB2
2. At present, because the SJA1110 S32 SDK is being applied for, I downloaded Godvip1.1.0 from the official website. From the user manual, I saw that the supported linux bsp version is 39, and extracted the sja1110 firmware from it. So I also downloaded yocto's bsp39 in my linux environment, and modified the build/conf/local.conf file, added the paths of sja1110_uc.bin and sja1110_switch.bin, and finally compiled and generated the .sdcard file, burned the image to my SD card, and finally loaded it in S32G2-VNP-RDB2. I set SW12 to 1-0 and started from norflash. Finally, I found from the serial port log that the SJA1110 function was not enabled. I put the log in the attachment. Please help me analyze the reason and give suggestions. Thank you
3. Finally, I would like to ask, for the development of SJA1110, my understanding is that data is written to SJA1110 through SPI, so it should be feasible for A core or M core control;
3.1 But why do I see in the forum that everyone is basically developing based on A core?
3.2 If you want to modify the port function of SJA1110, how should you modify it?
Please give me some suggestions, thank you~

After reading this article, I chose to put sja1110_uc.bin and sja1110_switch.bin in /lib/firmware, and the log is as follows

hi，jiajun_cheng

Thank you for contacting us.
1. I will further test the problems encountered in put sja1110_uc.bin and sja1110_switch.bin in /lib/firmwarene.Thank you  for your information.
2. In addition, Refer to UGS32G-VNP-RDB3-ethernet-enablem-guide.pdf (3.sJA1110 Port Configuration) Section 3 (download link S32G-VNP-RDB3 Ethernet:S32G-VNP-RDB3 Ethernet Enablement User Guide). The  User Guide describes how to configure port functionality for SJA1110 using the S32DS.
3. I think data is written to SJA1110 through SPI, and it should be ok to control SJA1110 with A core or M core. I will conduct internal consultation on the specific reasons and reply to you as soon as possible after getting the result.

Hope it can help you.

Hi， @Joey_z :

In the afternoon, my SJA1110 SDK application was approved, and I followed" S32G-VNP-RDB3 Ethernet Enablement Guide"Loaded switch_uc.bin.For the configuration of sja1110, is there any article for RDB2 development board.Is there any article that explains it in more detail?

hi，jiajun_cheng

Thank you for your reply.

For details, see 4. SJA1110 Port4 PHY Speed Configuration in the S32G-VNP-RDB2 Reference Design Ethernet Enablement Guide (download link：S32G-VNP-RDB2 Reference Design Ethernet Enablement Guide)

In addition, “Upload successfully verified” means SJA1110 image loaded successfully, and SJA1110 Port will work on your configuration

Hope it can help you.
