Hi,

According to datasheet Below

• MPC5744P Reference Manual Addendum, Rev. 2
• MPC5744P Reference Manual, Rev. 6

 

 

When entering boot modes, is there any method to run program? Even though, FAB(Forece Alternate Boot) been set as 1 by Hardware.

 

Reference Manual  2571page

Hi,

if FAB pin is pulled up during reset, the serial boot always starts. The application loaded in the flash memory won't be executed. There's no way to force the application to run in this case. It would be necessary to load small application via serial boot and that application would just jump to entry point of application loaded in flash. But it doesn't sound like suitable workaround...

Regards,

Lukas
