MSP430F5508: Device reset after entering BSL from software on Rev F chips.

Andrew Tesler

Part Number: MSP430F5508

Dear support,

I have a device with the below command to enter to BSL. The below command worked with over 1K of devices in the field, but in the new batch assembled the MCU instead of entering BSL reset itself immediately,

USB_disconnect(); // Disconnect USB device
__disable_interrupt(); // Disable global interrupt
((void (*)())0x1000)(); // Set the bsl address

The only difference I noticed is MCU revision 'C' in the old batch and now this revision 'F'.

I also resoldered the Revision 'C' MCU that I left on the new Assembly and the problem resolved.

I didn't find anything in the errata, please assist.

Regards,

Andrew.

Have you try the hardware BSL trigger to see if this issue happens?

Hi Gary,

Yes, tried and no issue here as with entering BSL when the device empty.

But I can't use the HW solution as this is already enclosed product and I need to drill a hole to be able to reach the correct pin.

Regards,
Andrew.

Hi Andrew,

to assess the problem you had, I need more information to reproduce the issue.

- are you using the TI factory BSL which is in this case is USB BSL?

- which host are you using to download the application? is that BSL Scripter?

Dear TI,

Can someone address this issue or confirm this issue with the chip so another project won't suffer as I did?

Thanks,

Andrew.
