Hello!

 

I want to read/write eeprom area via BDM mode. Main problem is with connection

I didn't receive any answer from processor. I'm waiting for 150cycles ect ect... but I didn't reiceve any data.

 

Can you look on attached file, and write me suggestions?

 

Perhaps is problem with reset time? I don'f find any documentation with detailed explanation of DBM.

 

Test traget is MC9S12DB128 @ 4MHz clock.


Best regards!
