Is this a custom board? Have you followed the pin connection guidelines (https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/dp/max-10/pcg-01018.pdf)? Are you terminating all unused pins as recommended?

Although I've not come across this particular issue, I frequently to check that all the power pins are powered. Any that aren't may possibly be responsible for powering the configuration circuitry. The fact you appear to be able to program the internal FLASH suggests it is powered correctly. Is 'VCC_ONE' powered appropriately and cleanly?

You suggest that programming the .pof appears to work. Can I assume you followed the process described in the 'configuring max 10 devices using internal configuration' section (page 3-4) of the max 10 fpga configuration user guide (https://www.altera.com/en_us/pdfs/literature/hb/max-10/ug_m10_config.pdf)?

Cheers,

Alex
