Thank you very much for your reply.

because the value of CONFIRMATION is 43211234 under normal circumstances, but now after clicking the confirm button, the value of CONFIRMATION is 57B5327F, so following the steps you mentioned above, it is no longer possible to modify BMI, BMHDIF, CRCBHMD , After the CRCBHMD_N value, Lauterbach always reports a bus error and cannot be modified.

Under normal circumstances, a modifiable interface (I tried it with another development board)

Unable to modify in exceptional circumstances

Thanks!!!

Please read chapter 6.5.4.3.1 for further details. I have attached a screenshot to let you know what the confirmation words means. In above scenerio you need to Unlock the device again by clicking Unlock button. 

Try following steps:

1. Run Prepareonly script
2. click edit button
3. click unlock
4. configure the parameters again
5. click update
6. click write
