Core v22

Added by foft almost 6 years ago

Received my board today.

I tried to understand the flash chip problems. All I found so far is that it has a 64KB sector size, so I've added detection by id so that we can have one v2 core for both different flash chips.

  • Detect flash chip by id (sector size)
  • Added 1 cycle delay on pokey highpass filter input (makes settings 5/7 work on PDM)
  • Run pokey on final sub-cycle, rather than on memory access completed sub-cycle (reduces sample jitter)
  • Convert audio to signed for HDMI output
  • Display some flash chip info on F11 screen (chip id1/ chip id2/ sector size)
