What are the jumpers on the back of the PCB for?

Open RChadwick7 opened this issue 10 months ago • 1 comments

The two jumpers look like this might change the VID/PID so it would work with Saleae Software. Is this true? Or do these do something else?

hello, it's for control the boot mode of CY7C68013A, C0 or C2, you can check the datasheet for detail.

Hi, can you provide the instructions to flash the eeprom with the correct 8CH VID-PID to use it with Pulseview? Xie Xie!

As I understood if A0 is high (3V3) the I2C setting will be 0xC2. Which means it loads the VID-PID from RAM. image It means by default your LA does not rely on the EEPROM?

you can check these repos https://github.com/ribalda/fx2eeprom https://github.com/esden/fxload

Thanks! 🫡 image Which one I shall use to flash the eeprom to use the FX2LP with pulseview? And especially what would be the VID:PID and the correct command arguments you used on the nanoDLA? Something like this? ./fxload -D /dev/bus/usb/aaa/bbb -I firmware.hex -c 0x01 -s Vend_Ax.hex -t fx2lp

I have purchased this version below and would like to experiment a bit with different firmwares and try both pulseview and saleae's Logic SW... nanoDLA

I would extremely grateful if you add to the README the two commands to flash the EEPROM on NanoDLA:

  1. To dump the original EEPROM of the NanoDLA (as backup)
  2. To turn it into a Saleae Logic
  3. To restore the initial backup dump. To roll-back to the original NanoDLA. Thanks a lot! :)

Any suggestion is very appreciated. I would like to experiment with different FWs... but I prefer to be sure of the right commands and arguments.... before bricking the NanoDLA 😅

You can flash other firmware at will, this will not damage nanoDLA

ok, but what is the right command? Something like this? ./fxload -D /dev/bus/usb/aaa/bbb -I firmware.hex -c 0x01 -s Vend_Ax.hex -t fx2lp

here is an example run on Linux ./fxload -I /home/pi/oss/sigrok-firmware-fx2lafw/hw/sigrok-fx2-8ch/fx2lafw-sigrok-fx2-8ch.ihx -D /dev/bus/usb/001/015 -c 0x1 -s ./Vend_Ax.hex -t fx2lp -v

Thanks! Will have it a try!

Hey @minkione did you ever manage to flash the VID/PID?
