Part Number: TMS320F28335
Dear Champs,
We are using the following processor:
TMS320F28335PGFA
We are using the following flash:
S29JL032J70TFI010
While attempting to load the DSC software using Code Composer into external flash, I think a power supply sagged or glitched and everything froze.
When the coma was over, I was able to reconnect with the processor through JTAG, however, the screen that comes up and is requesting 6 or 7 hex passwords to unlock flash.
Is there a way to recover?
When I select the emulator, it usually asks me to select the frequency etc., but this window comes up immediately:
If anyone know that magic passwords to unlock this would help me out greatly.
Alan
Hi Alan,
It's possible your device is permanently locked since there was a power interruption during the flash programming/erase process. Below from the F2833x datasheet.
Which version of Code Composer Studio are you using? I haven't seen an 'Unlock Flash' dialog box on any of the later versions, so I'm assuming it's a little older.
You should check the device's CSM password locations using the Memory Browser tool in CCS (may need a newer CCS version) while connected to the device. The CSM passwords are at addresses 0x33FFF8 to 0x33FFFF. If they show up as all 0x0000 and you don't know the password values then the device is unfortunately permanently locked.
Best,
Kevin
