1. ch1 - written/read from DDR, ch2 - just comes through. Simulator output: ch2...ch1-ch2-ch1-ch2 Board output : i can see images changing, but when the compressor is turned on - ch1-ch1-ch1... Does the compressor drop frames (i tried to add a delay (still experimenting))?

1. "Somehow the last row address I can reach is 0x7ff. Trying simulation".
It's ok now - I was uncarefully modified 'descrproc' module.
2. Test frame is in DDR.

1. Somehow the last row address I can reach is 0x7ff. Trying simulation.

1. With a couple of counters removed the memory test eventually ran fine @96MHz (again with bit0 missing). Need to put constraints to that path.

1. Vact&Hact based on counters - test counter work - do not work
2. Make a memory test, through channel 3 have the ability to read all the DDR - Done, bit0 is not changing. Here's an example (other bits were checked @48MHz and they are ok).
Write DDR Sent array to Row 0x00000003 00030000 00030001 00030002 00030003 00030010 00030011 00030012 00030013 00030020 00030021 00030022 00030023 00030030 00030031 00030032 00030033 Read DDR Acquired data from row 0x00000003 00020000 00020000 00020002 00020002 00020010 00020010 00020012 00020012 00020020 00020020 00020022 00020022 00020030 00020030 00020032 00020032
3. Run a little (for 1 page) memory test @96MHz. This is before phase shift adjust...

1. It's not 10359A yet. 2. There are problems with storing the whole image in the DDR and reading it back. Sync signals were lost. The simulation is ok, but there are too small images. It could be:
a. Incorrect address range written to mcontr registers?! - save the last row address (for 1620x1200, it's near to (2^21)/(2^10 - number of columns in a row)= 2^11 = 0x8000; b. ...

1. @96MHz, data from sensor replaced by 8 bit counter - there are vertical lines - that means one of the bits is late. Add a phase adjust to the 1st DCM.
2. Apply low drive strength to all the pins interface 353.
This removed vertical lines from section 1.
3. DDR
MaxFrame = (2592x1936)x16 ~ (2^12 x 2^11)x16 = (2^23)x16 = 8M16 = 1 bank of MT46V32M16BN-5B
2008/03/19
1. Initialize/Write/Read DDR @96MHz
It's ok.
2008/03/18
1. make i2c work @96MHz
There's a suspicion it works unstable, so TODO is: a. read an internal counter b. write/read BRAM - done
All's fine. Next Step - Initialize/Write/Read DDR @96MHz. This was unstable because of the need to adjust phase.
2. make the image look like as if data doesn't go through DDR. There're small differences.
All's good Reg Address: 0x0835 Data: bits[4:0]=00001 - channel1 -> DDR -> 359 -> 353 bits[4:0]=00010 - channel2 -> DDR -> 359 -> 353 bits[4:0]=00100 - channel3 -> DDR -> 359 -> 353 bits[4:0]=01001 - counter (accompanied with syncs from sensor1) -> DDR -> 359 -> 353 bits[4]=1 - counter (accompanied with syncs from sensor1) -> 353
2008/03/17
1. Put all FFs to negedge.And verify it. - done
2. Make i2c channels switching work fine - it's ok? but ->
3. i2c first work @96MHz
2008/03/13
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.
2008/02/20
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
a. not marked 359 acquired data is 0x05020306 acquired data is 0x05060706 acquired data is 0x090a0b16 acquired data is 0x0d0e1f16 acquired data is 0x11121316 acquired data is 0x15161716 acquired data is 0x191a1b06 acquired data is 0x1d1e0f26 acquired data is 0x21222326 acquired data is 0x25262726 acquired data is 0x292a2b36 acquired data is 0x2d2e3f36 acquired data is 0x31323336 acquired data is 0x35363736 acquired data is 0x393a3b26 acquired data is 0x3d3e2f46

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
2008/02/14
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).
