RTC doesn't works properly with HAL enabled

stefano6641 — Fri, 09 Sep 2022 12:28:00 GMT

Good morning,

I have some problems with my iMX 1021 board with HAL enabled. The application failed to write HPRC register in SNVS bank, no error reported but data aren't set.

The same binary file, loaded on a bord without HAL active, works properly.

Some help?

Thanks,

Stefano

In addiction seems that LP_SEC_VIO and SV1 bits of HPSVSR register are high.

Another addiction: I can write in HPRC register just under boot, for some time. After that I can't do it. I'm not sure which condition lock the write on HPRC register.

BR,

Stefano

Hi,

First of all, sorry for the later reply.

I am not sure if you refer the MCUXpresso SDK example <snvs_hp_rtc> for RT1020?
