I got a new NetDcuA5. I connected my Laptop to this board via the USB without any problem. Everything worked fine. After that I copied some files to the "FFSDIK" Folder and used the "WinNDCUCfg" to make some settings in the registry. I used the same setting which I used for the NetDcu8.
After reboot, I could never get an USB Connection again. I always get the message "UNKNOWN DEVICE". After booting, the board hangs in a Programm which looks like an editor. There is a menu with "FILE EDIT HELP". Below the menu I can find the following text:
services <command> <parameters>
That is all. I can do nothing to leave it. My application does not start, the Laptop always says "UNKNOWN DEVICE" if I try to connect to the board via the USB.
It is possible fo me to get a RS232 connection. I can see all the boot messages. The board reacts to sending an "S"
This is a part of the settings I wrote into the registry:
reg open \Init
reg del value Launch80
reg del value Depend80
reg set value Launch100 string CheckAutoStart.exe
reg set value Depend100 hex 1e,00
reg set value Launch60 string services.exe
reg set value Depend60 hex 14,00
reg open \system\ndcucfg
reg set value Port string COM1:
reg open \Init
reg set value Launch80 string \FFSDISK\SGener_3.exe
reg set value Depend80 hex 32,00,14,00,1e,00
"SGener_3" is the application I wrote and I like to start.
Maybe the "services.exe" is the root cause of all the trouble? I am not sure if I need it. It did not make any problens with the NetDcu8, but it might make trouble with the NetDcuA5?
I would like to bring the NetDCUA5 back to the factory setup. When everything was new, I had no problems to connect to the board using the USB. So right now I only have the RS232 Connection to the boot loader. Is it possible to recall the factory setup via the RS232?
