Other Parts Discussed in Thread: SEGGER
We have PCBs using LM3S5B91 that need firmware fixes. Since this part
is obsolete, please note the part number on the title is different.
The manual configuration setting in the JTAG LM flash programmer works to program the PCB
most times. Some times uploading flash contents to a file and erasing the flash is needed
to start programming the board. After programming the board few times, suddenly it says
unable to initialize the MCU. Giving hardware reset, power cycling the board, restarting the
computer makes no difference, seems like the MCU is locked up.
Is there anything else that can be done to program this MCU?
Thanks,
Priya
