AM33 Does Not Start When Using Interrupts in the Boot Loader (321172)


The information in this article applies to:

  • Microsoft Windows CE Platform Builder 3.0
This article was previously published under Q321172

SYMPTOMS

Windows CE does not start if you use a boot loader that uses an AM33 interrupt.

CAUSE

Windows CE expects a value of zero at INT_CODE for the AM33 Trap Base Register (TBR) when Windows CE starts and constructs the interrupt vector table. If a boot loader uses interrupts before this point, INT_CODE is set to a non-zero interrupt number. This causes Windows CE not to work during the construction of the interrupt vector table.
