S32K328NHT1MJBSR MAPBGA289 Programming problems

[gary_yang]

Dear sir：

We are a third-party programmer manufacturer.

Currently testing programming the S32K328NHT1MJBSR.

After successfully programming the customer's file, the J-Link connects successfully,

but Erase fails.

If programming random code, erasing and programming can be repeated.

This is our programming circuit.

Do you have any suggestions?

Thanks

Hi@gary_yang

Based on the error message, you are attempting to erase the HSE area, which is likely the cause of the erase/write failure.

Dear Sir:

After programming a specific file, it cannot be repeatedly erased and programmed.

The entire IC cannot be eraseed.

If it's a programming random code, it can be repeatedly erased and programmed.

What is the address of the HSE area?

Thanks

Hi@gary_yang

I'm not sure if this is the cause; this is just my guess. It's also possible that the current sector is locked in your code.

However, regarding the HSE memory address:

int_pflash : ORIGIN = 0x00400000, LENGTH = 0x007D4000 /* 8191KB - 176KB (sBAF + HSE)*/

Last 176KB reserved for HSE, that is: 0x00BD4000~0x00BFFFFF。

I suggest you contact SEGGER's technical support.
