    Hi Mohamed,

    thanks for the script file. Yes, this file is not supposed to be edited by the user.
    Instead you can call it or portions of it as described in the upper comments.

    like this:
    DO ~~/demo/tricore/flash/tc37x.cmm CPU=TC377TE PREPAREONLY

    It seems that this script allocates address space for all BMHDs in DF0.

    Unfortunately, this might not really help.

    Do you have another custom board with another Aurix available?
    This would possibly help you overcoming this issue.

    If your BMHDs are corrupted or simply not exist, the only thing what you could do is manually rewrite them.
    What about the UCB0? Did you edit or erase it? Can you have a look on it in Trace32?

    Regards,

    Jens

    When you change line 256 from:
    FLASH.Create 21. 0xAF400000--0xAF4001FF 0x0200 NOP Long /INFO "UCB00 BMHD0 ORIG" ; DF0, DF0_UCB0
    to
    FLASH.Create 21. 0xAF400000--0xAF4001FF 0x0200 TARGET Long /INFO "UCB00 BMHD0 ORIG" ; DF0, DF0_UCB0
    Then the UCB0_ORIG will be programmed also when it is part of our program to flash.
    When you wrote 1 time the BMHD then you can revert the change as long as you don't change the BMHD.

    Hi MoD,

    nice trick. What about this comment?

    If changing the sector type from NOP to TARGET is required, use the command; FLASH.CHANGETYPE instead of modifying this script.

    When I get this right, Lauterbach is trying to prevent users from permanently locking their devices, which obviously happened from time to time.

    Is there any further documentation regarding this script available?

    Thanks for sharing this information.

    To prevent the device from permanently locking I wrote to change only configuration of UCB0. Risk of permanently lock only when you manipulate ORIG and COPY at the same time.
    As I understand he use only this script and not any other where he can make changes.
    For more documentation please see the doc folder in T32 or ask directly the Lauterbach support.

    Hi MoD,

    yes Mohamed should contact Lauterbach directly. We are more related to PLS tools for debugging.

    Make sure you don't leave it that way - UCBs should be kept under 100 program/erase cycles for maximum retention (see tRTUcc in the datasheet).

    Hi UC_wrangler,

    I assume Mohamed is aware of that. I think it was more like an accident loosing the BMHDs.
