dc9c6c9667 cpld: Stream CPLD data from host 
Previously CPLD programming involved a large 64kbyte buffer into which
the the entire bitstream would be completely downloaded, and at which
point the programming process would commence. This is needlessly
wasteful of memory. Moreover, it could lead to USB timeouts as the
firmware needs to wait the entire duration of the programming process
before returning an ACK to the host after the final SETUP data phase
packet.

Instead, we now receive 512 byte chunks of the bitstream and stream them
to the CPLD one at a time. We wait for each packet to be streamed out to
the CPLD before ACKing the packet to prevent active data being
overwritten.

1723cd12a1 Oops, read PLL1 documentation again. Looks like FBSEL=1 is for "normal operation". So include that, but use DIRECT=1 to skip the PSEL divider (which would prevent us producing 204MHz from an in-spec PLL frequency). 2013-05-11 12:25:54 -07:00

d9884af8b8 PLL1 was misconfigured to run at 408MHz (way out of spec) instead of 204MHz. Corrected this by using DIRECT=1 instead of FBSEL=1. 2013-05-11 12:11:37 -07:00
