Re: Has the FXCore chip on my Dev Board Died?

Frank thanks so much for the new Assembler. I followed your instructions and the results I got are as below. I don't have anyone nearby with the necessary eyesight and skills. Our team is located in different countries! Mick has suggested I try reflowing the solder joints on the FXCore chip in case ...

Re: Has the FXCore chip on my Dev Board Died?

The jumpers all seem to be in the correct places and of course I hadn't changed any but always worth checking nothing had moved. The clock signals are all correct, which must mean the FXCore is powered up and at least the clock generation section is working: Oscillator Clock: 12.288MHz MCK (checked ...

Hi Frank and thanks for your suggestions. I've added some of my answers (ALL CAPS) to the questions below. I'll remember to use your email for contact in future 8-) *** As regards my mention of the FT260, that might be me getting confused and misquoting what I read! The Microsoft USB View app shows ...

My Dev Board has suddenly stopped working: no sound, no flashing LEDS with a program that has tap tempo so should be flashing etc. Until yesterday I have been able to trial code by assembling and uploading via Notepad++ but today, without changing anything I am getting this error ......................

Re: Need help with writing to FLASH problem

Yes! Adding a 200ms delay after the WRITE_PRG command did the trick. I also removed the RETURN_0 command but that was not necessary as it now works either with or without it. My guess is that, without sufficient delay after the write command, the FXCore is still writing the data to flash when the EX...

Re: Need help with writing to FLASH problem

Thanks to both of you for your helpful suggestions. @Frank: I removed the RETURN_0 after the write command but it didn't help. You're correct about the 'error' value, It's being returned from the I2C library and it corresponds to a 'NACK (Address)' error. @DisasterArea: As far as I can tell, I'm doi...

Need help with writing to FLASH problem

During a Firmware update of our new pedal, we have a routine to flash the updated DSP programs to FX Core Flash memory. The problem I'm seeing is that, after all the programs are written to flash, which works correctly, there is no sound until I manually reset the FX Core Dev board by momentarily gr...

Re: Command line assembler

I have created a Windows cmd script and a Sublime Text build that will get the Assembler to program a specified location in the FXCore Flash memory. You will have to install the 'Terminus' package in Sublime Text since its own terminal window is not interactive, so, although you can type in a locati...
