S32G2 doesn't work and RST ERROR

zhipeng — Thu, 04 Sep 2025 10:47:26 GMT

I use S32G2 and its PMIC (VR5510) ,Refer to the S32G-VNP-RDB2 scheme.

The voltages are correct.

But the S32G2 does not work

The system image is in the TF card, and LPDDR is not installed yet

What could be the problem?

Hello, @zhipeng

Thanks for your post.

So the schematic of your custom board is similar to RDB2, but without LPDDR4 installed? The DDR interface pins are left unconnected on board?

What kind of the image on the TF card? how they are generated?

Hi Chenyin,

Thanks for the reply.

The schematic of my custom board is similar to RDB2，but because of the DDR hasn't been bought yet, it is not installed。The DDR interface pins are left unconnected on board。

the image on the TF card is made by the installation instructions, the following two, are the same problem.

What could be the problem?

Thanks very much！

Hello, @zhipeng

Thanks for your reply.

1. You are willing to booting the board via SD, is it right? if yes, also measure the clock of SD

2. From the wave you captured, seems there is abnormal pull-down signal on RESET_B.

3. If confirmed no issues from HW, use the debugger to attach to the board for further analysis.

Hi Chenyin,

Thanks for the reply.

Yes，I am willing to booting the board via SD，The captured waveform is as follows.

2. There is no pull-down HW setting on RESET_B.

3. Can I use S32 Debug Probe debugger?

Thanks very much！

Hello, @zhipeng

Thanks for the reply.

Yes, the S32Debug probe could be used for the S32G2 via JTAG interface

Hello, chenyin_h

Thanks for the reply.

I have bought the debugger. Using it， can run MCU programs on the M7 core, but the A5 core still cannot run the system. Do I need any additional configuration or programming?
