F29H859TU-Q1: How to realize the LPOST/MPOST?

Hi,

Shuqing Zhou said:

nd when we run the demo, the LPOST_COVER is 00, that means the LPOST isn't enable, but the test result is pass, why this is happen?

The EMU_BOOT_DIAG register is not relevant and does not reflect the LPOST/mpost enable/disable.

Since the status shows A5 it means the SECCFG programmed currently has the LPOST and MPOST enabled.

Could you program the SECCFG without post enabled and check the SECCFG to ensure its not enabled.

Yes the description in safety manual is correct.

Hi Prarthan,

what's meaning of LPOST_cover?

Hi,

As I said before this register EMU_BOOT_DIAG is not used and not relevant. We are removing this register from upcoming releases.

Please refer to SECCFG programmed and the POST results after power-up to see the status as mentioned in safety manual.

Thanks

Hi Prarthan,

Hi Prarthan,

Marlyn send me the updated SECCFG memory description.

Addition question: is LPOST/MPOST just happen in SSUMODE2/SSUMODE3? Can it work in SSUMODE1?
