MSP-GANG ERROR23: MCU device init (Using BSL interface)

Other Parts Discussed in Thread: MSP-GANG

Hi all,

I am considering the programming using BSL interface of MSP-GANG programmer.

The JTAG interface, you can read the main memory, but in the BSL interface, it becomes ERROR23 If an attempt is made to read.

I am referring to the documentation below for BSL interface.

・MSP Gang Programmer (MSP-GANG) User's Guide
　 Figure 2-11. Memory Options, BSL Sectors Selected (page 30)
　 Figure 5-6. BSL Connection SchematicBSL Connection Schematic (page 101)

The firmware version, in 1.1.8.0,Password space is all 0xFF.

I am receiving an error ERROR23: MCU device init, and I have no idea what this means or how to work around it.

Regards.

    You are using BSL as your interface, but you do not need to program your BSL area, correct? You wouldn't be able to program the BSL area while you are using the BSL as your interface, because you would be erasing the BSL area where you are currently running the code that's letting you access the device via BSL.

    • If you need to program BSL area for some reason (load your own custom BSL for example), then you should use a different interface like JTAG or SBW.
    • If you don't need to alter the BSL area, then you can use the BSL interface but do not select the BSL segments in the memory options especially for erase/program/verify (because you need the BSL to stay loaded and unaltered in order to access the part via BSL).

    Do you think you might have accidentally erased your BSL? If you use JTAG, can you read out the BSL area and confirm that it is still there?

    Regards,

    Thank you for your reply.

    BSL was not erased.

    I tried to re-check the wiring. Then, I can be described by the now BSL.

    Regards.
