MSP430F5529: Invoking BSL (jump to 0x1000) results a reset (Security violation (BOR))

Hi,

I'm trying to upgrade the FW using the default BSL via USB.

Each time I invoke the BSL by jump to 0x1000 I get reset due to Security violation (BOR).

I'm sure that it's a SW issue because when using the C1_LedOnOff demo it works good.

Any reason why invoking BLS will result reset?

Thanks,

Itay

Solved.
I had to disable the Oscillator fault interrupt.
Just added SFRIE1 &= ~OFIE; before invoking the BSL routine (((void (*)())0x1000)();)

Hi Itay,

Glad you were able to solve your issue. Usually we disable all interrupts before going to the memory address. Here's a screenshot of the section in the BSL User's Guide.

Well, I tried that first but it didn't work (__disable_interrupt(); before invoking the BSL).

Not sure why.

Thanks anyway.
