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 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, 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.
