ATLYS programming FX2 lost configuration

[dsperlich]

Hi,

my ATLYS baord is not detected by an operating system any more as valid USB device when connected to the PROG mirco usb port. On linux i see for example:

[85564.500749] usb 2-1.2: new high-speed USB device number 80 using ehci-pci
[85579.582195] usb 2-1.2: device descriptor read/64, error -110
[85594.764710] usb 2-1.2: device descriptor read/64, error -110

 

I played now a little bit with it, and are pritty convinced that the content of the EEPROM for the FX2 is damaged. Sadly i cannot find a copy of the eeprom content for atlys on the internet. I actuallys found one from an nexys 2 board and when i flash this with the FX2 software on the eeprom, the atlys is recogniced again even with adept, but this old version does not seem to support all features needed by a reacent adept. I mean i can configure my bitfiles, but when i try to flash them, adept tells me that the communication with the FPGA failed.

 

So is there somewhere the firmware of an ATLYS FX2 availiable, so i can recover my ATLYS properly?

 

Cheers

Hello @dsperlich,

You can try to reprogram the Atlys. I will send you in private message the link to the FX2 and procedure.

Best regards,

Hi,

 

thanks for the tool. For future reference i found now, that the problem was not the NEXYS 2 version of the FX2 firmware (file called donbusb.iic if you want to search the internet :-), as it looks like digilent does now want to distribute the firmware publically any more even though they did it in the past with Digilent_USB_Firmware_Upgrader.exe), but the digilent tool is nicer to use than the cypress tools. The problem was missing solder connections when i soldered a new FX2 on my atlys, as i first suspected a broken USB frontend as probing with a scope showed that the eeprom was still read properly.

 

Cheers

I actually have the same problem, sorry, it happened after i was messing with trying to run some HDMI2USB stuff on the atlys, it now no longer is recognized in Device manager or in Digilent Adept, can i have the eeprom contents via PM too ? The donbusb.iic is no longer even on the internet so i cant try with that one..

Hi @rajkosto,

Here is the DigilentFX2Repair.rar.
