2.1.2 Flash memory fault indicated
YES
YES
FLASH programming does not work
YES
If the fault information from the prommer is:
a) The flash manufacturer and the device IDs in the existing Algorithm files do
not match with the IDs received from the phone.
b) The External RAM test failed in the Phone.
c) The Phone does not send acknowledge signal (ie. drop the Flashbus TXD
line to low state) after the Prommer has sent the Algorithm code.
d) The Prommer has detected a wrong ID byte in the MCU_ID_RESPONSE
message, which it has received from the Phone. See Note.

YES
Figure 6.
Note: Wintesla shows the following Flash ID’s for every flash device when
programming is going on.
If Flash ID bytes are correct the following bytes are shown:
Flash ID 0089–8896, 0089–8896, 0089–8896, 0000–0030
=Flash 0 =Flash 1 =Flash 2 = SF
But if one or more of Flash ID bytes is/are wrong the Flash is faulty or there is
short circuit in the flash interface.
