In production, the first programming is done via panel connector X201. After this, the
panel connector is cut away, thus other flash programming must be done via service
interface J100 - J105.
The main differences between these are:
a) FLASH programming voltage is produced different way.
b) Signal routings are different.
The fault finding diagrams for flash programming are shown in Figure 4–3, Figure
4–4 and Figure 4–5.
In flash programming error cases the flash prommer can give some information
about a fault.
The fault information messages could be:
– MCU doesn’t boot
– Serial clock line failure
– Serial data line failure
– External RAM fault
– Algorithm file or alias ID don’t find
– MCU flash Vpp error
