The issue encountered when programming the POF file into MAX10

After powering on my FPGA development board, the power status LED did not light up, so I checked it and found that the issue was with the MAX10 chip. I then planned to reprogram the MAX10 using the m...

Hi Xingyunzhidi,

​

1- May I confirm with you again which LED this "power status LED" is referring to? Is it D6? What actions have you done before the failure happened?

2- Please check SW8 again to make sure the MAX 10 is enabled in the JTAG chain.

3- Is the LED D14 lit up or not?

4- If the M10_CONF_DONE indicator D14 is not lit up, and you still can not program the MAX 10, then one possibility is that there's something wrong with the power supply on the board. Then you need to check the schematic and find the measure point of these power supplies.

Best Regards,

Xiaoyan

  1. Yes, I mean D6.
  2. I set SW8 to OFF/ON/ON/OFF.
  3. D14 is lit.

Where could the issue be?

    Hi Xingyunzhidi,

    1- Make sure again you are using the micro USB cable to plug into J8 instead of using USB blaster.

    2- Could you measure the voltage at the pin1 and pin_3 of the SW8? Just to confirm whether there could be anything wrong with this Switch.

    Pin_1 should be ~3.3V.

    Pin 3 should be ~0V (the USB_MAX_JTAGSEL signal should be 1'b0 to enable MAX 10 JTAG).

    It could be a bit difficult to confirm where the pin_1 is, but you can understand from the schematic that the pin_8 and pin_7 are ~0V.

    Best Regards,
