Now there is a strange event.

I use STR911FAM44X6, I let bank 1(32k) be bootloader, bank 0(512k) be main program.

I found when program running in main program, and I let RESET_INn pin short to ground for a while, the IC can't be RESET normally.

But when I run in bootloader the reset is OK.

Do somebody know why and please kindly advices me!

Thank you very much,

Hi,

Please could you mention the silicon Revision, you are using?

If it's a Rev G device or lower, hence it's a known issue already reported in the current Errata sheet (see section2.3)

Kind regards,
