Part Number: TMS320F28P650SH Tool/software: We are testing the robust of the bootloader, we disturb the flashing(after flash is erased, the DSP is writing data to the flash) by disconnecting the power supply for the whole system. Then recover the power supply for the whole system, the DSP is re-powered, but the code is not run into the main function. I use a debug GPIO to toggole in the main function, but the GPIO level is float, not toggle. Is there any limitation for the DSP lock when the flash is updating?
