I got one last week, it works a treat !. Both SPI Flash programming and CRAM work well. I added the missing PLL cap too. I hope the internal oscillator can drive the PLL reliably to be able to drive a VGA monitor.
One thing I didn't look up properly is that the block ram in simple dual port: one read and one write port. Reading the docs is an advantage
, I should have done it earlier !.
To program it I bought a FT2232H board from aliexpress, it works with diamond programming very well. I had to re-program the EEPROM attached to the FT2232H to make it compatible.
I just wonder how low power are these things in reality...
