    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,

    K

    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,

    Eris.
