I'm using GCX v4.20.16

I'm trying to use serial mouse

I have done modification to the adsload.hwt & adsload.reg
0xA1E3004C 0x00000001 ; MouseDetect enabled

;-----------------------------------------------------
; Serial mouse
;-----------------------------------------------------
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\SerMouse]
"Index"=dword:1
"Dll"="SerMouse.dll"
"Prefix"="MSE"
"Order"=dword:B
"EnableMouse"=dword:1
"FriendlyName"="Serial Mouse"
"Port"=dword:1

I still have the following error during boot
Initializing Serial Mouse Driver...failed.

I also look at the Windows folder just to confirm that SerMouse.Dll is there

any idea

Thanks

Thanks for the details. Very helpful.

It's possible that there is a power problem. COM1 is a 5-wire serial port, which might not supply enough power on the RTS line to drive the mouse fully. Have you tried connecting the mouse to COM3 of your GCX? It's a 9-wire port that offers both RTS and DTR as power sources for the mouse (see details at topic 151).

Looking at the debug messages, I see that it's not reporting the usual: "SerMouse : No mouse found. Returning serial port to original status.", so something is happening with the mouse driver. It's not clear if power problems are creating communication problems, or if the driver is having some other issue.

I would try the following:
(1) Confirm that when you disconnect the mouse, you get the "No mouse found" message.
(2) Change the registry to use COM3 for the mouse and the HWT file to route the debug output to COM1.

Hi

I've got the same problem event with no mouse connected to the device

Here's the initialization
==================================================
itializing Ethernet Driver...ok (0ms)
Initializing Serial... COM1 ok. (102ms)
Initializing Serial... COM2 ok. (102ms)
GetSerialObject - 4
Initializing PCMCIA Driver...ok. (408ms)
Initializing CAN Driver v1.4...ok (33ms)

Initializing I2C driver v 1.1...ok (2ms)

Initializing PXA25x Display Driver v. 1.1...ok (426ms)
Initializing PS/2 Driver...ok (0ms)
Initializing Touch Panel driver v 1.3...ok (223ms)

==================================================

I didn't try to connect to the COM3, if the driver doesn't work I'm not sure it will help (however I will give it a try in the next few days)

Thanks for you're help

Phil
