Hello All,

I am working with two different applications - boot loader application and main application together. The bootloader size is limited to 64k and the main application start address  changed to 64K. The jump to the main application from bootloader works fine(jumping to 0x00010000) . But when I am trying to jump to bootloader start address  0x00000000 from main application I am getting the error response as ''Unknown break cause'' in UDE,Please find the attached Error Screenshot.

I am using SPC560B54L5 EVK along with SPC5Studio 5.2.3.

I am attaching my example test applications for your reference kindly check and provide your suggestion for resolving the issue.

Thanks in Advance,

With Regards,

R.Santhamurthy

Sorry for the late answer ,

To debug an unknown break cause , you should put UDE in the mixed mode.

And analyze by assembler routines.
