Hi,

I'm trying to get up to speed using an EICO module. I have a simple test program that compiles and sims OK. When I run EICO programmer, it finds the EICO module on the USB, it can read whatever is in the module, and erase the module. However, when I send the program, it halts before completing the send and tells me 'send failed'. I tried to open the EICO programmer help file, but for some reason it can't find it (tries to get on line it seems, and that fails, although I am connected to the 'net).

Any pointers to what might be going on? Also, what exactly is the significance of the blinking LED on the module? It keeps on flashing while sending the program, is that how it should be?

Thanks for any help,

Jan Didden

The blinking LED indicates that the device is trying to connect with the PC or that the device is being reprogrammed.

Are the drivers for the ECIO installed correctly? There should be a "driver_install.exe" file for the ECIO that needs to be run before attempting to connect the device.

Hi Steve,

I uninstalled, then installed the driver sucessfully. When opening the EICO programmer app I get:

USB Write Failed
Failed with error 6: De ingang is ongeldig. ['The port (?) is invalid']

ECIO-28 version: (????)
Ready
ECIO not found!
ECIO not found!
ECIO-28 version: 1.1
Ready

Then if I open the .hex I wish to download to the module:

Program has been loaded

Then when trying to send the program:

Sending Program...
Send Failed
Ready

Any pointers?
Edit: The module shows up correctly in the hardware manager.

Hello Jan,

Sorry, but I don't know about this error. Please try downloading the attached program (use the FCF to download via Flowcode and the HEX to download directly using the ECIO-prog utility) and see if these work. The program simply puts 0x55 onto portb.

You may get the error messages, but the downloading might work ok. Please tell me if you see the 0x55 pattern on portb after downloading the program.

Steve,

Neither method works. Both attemps lead to the same error message 'Send failed'. The portb pattern doesn't resemble 0x55.

Edit: tried changing the supply jumper from 'external' to 'usb'. No change.

Sorry, Jan. I really don't know what the problem could be. Are you able to try on a different PC?

Steve,

Got it going. The problem is somewhere in my app. When I run the EICO module on itself, powered from the USB, the program loads fine.
Should have checked that first....
