Serial Reprogramming (Flash Writer)
The M3A-8K02 board allows the user to reprogram the 38K0/38K2 Flash chip on board (serial
reprogramming of F/W) using a flash writer.
To perform serial reprogramming, insert the flash writer cable in the flash writer connecter (1), set the
VCC-SELECT switch (S7) to 5V, the BOOT-MODE switch (S10 in 2) to P42 = “H” and P16 = “H”, the FLASH
switch (S9 in 3) to ON, and then apply external power (or USB up-port VBUS power). Follow instructions for
the Flash writer to continue with the reprogramming process.
Note 1: Multi-Flashwriter
= MFW-1 (Sunny Labs)
Note 2:
A separate flash writer and reprogramming
adapter is necessary for parallel programming new
firmware in the 38K0/38K2 boot ROM area.
