[edit] Flashing the Milkymist One

  • Reflash Milkymist SoC bitstream & BIOS: Please follow the procedure of this email. Back up here.

[edit] Pre-test on RC1 board with err-batch

Flickernoise 0.1 (built on Nov 19 2010)
OS: RTEMS 4.10.99.0
Plateform: Milkymist SoC 1.0RC1
CPU: LatticeMico32
Board: M1 (PCB rev. 0)  << RC1 board
  • Current(without U21 video codec): 0.3A after initialization(D2 light off). 0.42A during run batch commands. 0.61A while run BIOS after power up(D2 light up). More current check RC1 report[2].
  • Current(with video codec): 0.42A after power up(D2 light off). 0.84A after booted. 0.87A while running Flicknoise 0.1(D2 light up).

[edit] Report of Milkymist One RC2 Board

  • Some IOs won't be tested: J3(pin 5 ~ 18), J21 and Blue/Red RCA connectors of J18.
  • About while running Flickernoise 0.1 on M1 RC2 board. Each Milkymist One Board has its own MAC address, check IEEE OUI 10-E2-D5(hex).
  • Current 0.54A without REFLASHING any software porting and any IO cables.
  • Current 0.56A with REFLASHING & without any IO cables.
  • Current 0.44A standby for boot.
  • Current 0.74A while test program run with all IO cables.
  • Current 0.84A while Flickernoise run.
