The main differences between these are:
• FLASH programming voltage (Vpp) is produced a different way, and
• Signal routings are different.
The fault-finding diagrams for flash programming are shown in Figure 2, Figure 3, and
Figure 4.
In cases of flash programming errors, the flash prommer can provide 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
