S32K312 - How can I wrtie UTEST area?

[ssean]

Hello.

I already test HSE_DemoApp and it working well.

But I want to write UTEST(0x1B00 0000) area without HSE_DemoApp, in my program.

I load FLS example on S32DS and add UTEST sector like below.

But error occured.

1. Is there some solution for write UTEST area using FLS or other MCAL driver?

Best Regards,

SEAN SUNG

Hi @ssean 

Check the following community post. This explains how to program with the C40_Ip_Example the field CUST_DB_PSWD_A (UTEST memory field located at the addresses 1B00_0080h). This might be useful for you.
