I have a CG Pro 9S12, recently I used it to do BMW FRM E-series, CAS3 OL15Y, BMW–EWS4 1L86D 2L86D. There were something wrong with it during the operations.
Problem 1: When i did BMW FRM E series, an error message appeared “This partition size is zero, can not operate…”
Problem 2: When i tested BMW Cas3 OL15Y dashboard, it prompted “BDM connect failed, please make sure the line is connected properly, or try to decrypt the chip.”
Problem 3: When i tested BMW EWS4 1L86D 2L86D dashboard, it prompted “Decryption timeout”. i tried it for four times, the first three times all appeared the “Decryption timeout” message, while it was successful in the fourth time, but i didn’t change anything. The operation was same as the first 3 times like the connection, but until the fourth time it worked successfully.
As for the three problems above, cgdishop.com engineer offers the corresponding solution.
The solution for problem 1:
It needs to partition EEPROM and DFLASH when reading and writing BMW FRM E series.
For setting BMW FRM partition, EEPROM can set max 4KB (Dflash is 0 ) or Dflash max 32KB (EEPROM is 0).
Please refer to the post to learn the related operating guide.
