Re: [time-nuts] FE-5680 Linux command line tool
I use that chip in an old project with an 8051 microcontroller. They are becoming obsolete, I had to switch to the PSD913F if I recall correctly (or maybe the other way around?) I have a couple of the programmers too. They work from the printer port, you are talking about certifiable dinosaurs :) Didier KO4BB On October 11, 2014 3:19:52 PM CDT, Tom Wimmenhove wrote: >It's a chip (PSD813F) which has 1MBit flash, 16Kbit SRAM and 256Kbit >EEPROM.

Re: [time-nuts] FE-5680 Linux command line tool
It's a chip (PSD813F) which has 1MBit flash, 16Kbit SRAM and 256Kbit EEPROM. It's old school with parallel data/address bus and all that :) It does have JTAG.

Most EEPROMs have I2C or SPI interfaces. Some Flash chips have JTAG.

Re: [time-nuts] FE-5680 Linux command line tool
I haven't looked at the EEPROM dump, so I can't help you with that. Perhaps someone else can. One place for various adapters to program chips is MCU Mall. I have purchased from them a few times. http://www.mcumall.com/comersus/store/LeftStart.asp?idCategory=30 It they don't have the size SMD clip you need, you'll have to Google. I bought a few elsewhere years ago, but don't remember where.

Re: [time-nuts] FE-5680 Linux command line tool
Thanks Joe! I don't have the clip-ons but of course I could get them. I know the chip has a JTAG interface, but I've only used JTAG with chips that came with a programmer and software :) (except with OpenOCD over parport once, but that was in the stone age). Another question about the EEPROM dump Elio Corbolante. The chip has a 256Kbit (32KB) EEPROM and the dump is 160K: -rw-rw-r-- 1 tom tom 160K nov 8 2012 FE5680A_EEPROM.bin Which part in this dump is the actual data from the EEPROM? Thanks in advance.

Re: [time-nuts] FE-5680 Linux command line tool
I don't know how crowded the board is, but I would use an SMD DIP clip instead of unsoldering the chip.

[time-nuts] FE-5680 Linux command line tool
I recently came across a thread on this list about undocumented FE5680 commands. I have been using a little linux command line tool I wrote years ago for tuning the unit and decided to add these commands to it. Since this mailing list was the place I found the unit (someone linked to an ebay seller) I figured I' d join the list and throw it on here :) http://www.tomwimmenhove.com/otherstuff/fe5680-0.2.tgz Now, the bad news. I had my unit running overnight while logging the serial command output that reads the ADC, and in the morning it was no longer locked. The 10MHz signal disappears about 5 seconds after power-on, and programmed offset was somehow reset to zero (it had been set to -645). So it appears as if the internal EEPROM has been corrupted. I read a post from Elio Corbolante where he posted EEPROM and firmware dumps. Anyone have any idea on how to re-write this firmware back into the EEPROM by hand (would this be possible through JTAG, or do I actually have to solder the chip out of there? :) ) Or maybe there's someone willing to sell their broken unit I could take the chip out of?
