TODO:

1. Mistakes during reads?! Check read and write addresses.

!!!! FORGOT TO INITIALIZE CHANNEL 2 !!!!

This chain works fine now - "sensor -> channel's 0 buffer -> DDR -> channel's 2 line buffer -> to 353"

2008/03/12

1. DDR channel 3 has no problems @48MHz

2. DCM stops working after first try to get the image. It needs to be reseted.

(Address:0x810, Data:0x00000001)
(Address:0x810, Data:0x00000000)

3. Simulation model works fine: the stream from "the 3rd" sensor is written line by line to DDR and is read back (line by line as well).

4. The board doesn't work properly (behaviour is different from the simulation model's ).

a. data written to buf0 is ok
b. data read from buf2 is not.

1. I2c check

a. It doesn't work when assemled with mcontr and 2 DCMs.
b. Started from the beginning. Works.
c. Checked i2c four read with 1 start. Works fine.
d. Adding DCMs.

2. Check BRAM read/write. All's fine

3. Check DDR read/write. Some problems. not solved All's fine now

4. Three different boards operate identically: BRAM - ok, DDR - not

Channel 3 (test channel) now works fine. And DDR is ok now.

2008/02/20. Understanding how 353's mcontr works

02/28/08: 15:04 for mode=0 ( 8 - burst length)

TileX - number of (32x8) blocks
Seq_par(or Param) - the last write block length - (Seq_par)x8
TileY - number of TileX
All this starts from StartAddress

1. Channel 3 simulation:

• DDR initialization through i2c - done.
• write to DDR - done.
• read from DDR - done.

2. PHASE_SHIFT in DCM is not available currently, because the model had bad constructs, but SDCLK(SDNCLK) can be controlled by "phsel".

For correct writing/reading from DDR in model set phsel="01" (register=0x1008, value=0x00000004).
