The main page for the board is 10359.

10359 work journal.

Summary

1. DDR test and phase adjust

2. Switching channels

3. Buffering one frame in DDR and switching between two channels (frame by frame, one buffered, one direct).

Working with 10359

If any of the mentioned scripts is missing (currently it is 'switch_to_dcm1.php' and 'snapshot_mode_init.php') update CVS and copy it to camera. destination is: 

ftp://192.168.0.9/usr/html/359

Snapshot Mode

Currently works for 3 sensors

1. Power on or reboot, then refresh (I'll use the default ip address of the camera) 

http://192.168.0.9/

, this will initialize the first sensor

2. Initialize sensors and carefully adjust phases starting from channel 1: 

http://192.168.0.9/359/sensors_init.php
Repeat for all channels:
Channel 1:
 http://192.168.0.9/359/reg_write.php?adr=0x835&data=1
  adr         - register address, 0x835 - "channel" register

 http://192.168.0.9/359/phases_adjust.php?dcm=1&phase_shift=1&n=5
  dcm         - number of DCM to use ('1','2','3' - same as channel numbers)  
  phase_shift - '1' - "+"-step, '2' - "-"-step
  n           - number of steps

 if colors are inverted try
 http://192.168.0.9/359/phases_adjust.php?rst=0&sphase=0x6
  rst=1                - reset all DCMs
  sphase[i]=1(default) - channel 'i' latches Vact/Hact on the FALLING edge of sclk0, sphase[i]=0 - RISING - KEEP SPHASE BITS FOR OTHER CHANNELS UNMODIFIED
 (not helps - keep shifting the phase)

Channel 2:
 http://192.168.0.9/359/reg_write.php?adr=0x835&data=2
 http://192.168.0.9/359/phases_adjust.php?dcm=2&phase_shift=1&n=5
 http://192.168.0.9/359/phases_adjust.php?rst=0&sphase=0x5 - if colors are inverted

Channel 3:
 http://192.168.0.9/359/reg_write.php?adr=0x835&data=4
 http://192.168.0.9/359/phases_adjust.php?dcm=3&phase_shift=1&n=5
 http://192.168.0.9/359/phases_adjust.php?rst=0&sphase=0x3 - if colors are inverted

3. Put the first sensor in the Snapshot Mode: 

http://192.168.0.9/ccam.php?trig=async&mode=set

4. Reinitialize everything (look up in source, also some kind of log will be on that page) 

http://192.168.0.9/359/tests_for_96mhz.php

Procedures:

- set delay between trigger signals to sensors (1 step is 96MHz period). Default is 0.

- initialize other sensors (Parameters from sensor 1 are taken)

- send initialization sequence to DDR

- proper channel is selected (0x10001, in fact it is mode)

0x10XXX (XXX is 001,010,100) - for switching frames from sensors on the output. One direct, one buffered.

0x00XXX - frames from one channel (depends on XXX) go directly to the output

- set frame resolution

- initialize memory controller channels

5. Start the compressor and get a couple of frames 

http://192.168.0.9/compressor.php?cmd=run 
http://192.168.0.9/sync.php?role=self&fps=single

for another couple refresh the second link.

6. The frames will be written to the circbuf 

http://192.168.0.9:8081/pointers/ - will show some useful info
http://192.168.0.9:8081/torp/next/img/save - surf the circbuf
http://192.168.0.9:8081/torp/prev/img/save - surf the circbuf

7. To stop the compressor 

http://192.168.0.9/compressor.php?cmd=run 
http://192.168.0.9/sync.php?role=self&fps=single

It stops after it gets the next piece of data - that will be two frames in this case.

Some other scripts and modes

1. after power is on, go to (I'll use the default ip address of the camera) 

http://192.168.0.9/camvc.html

, this will initialize the first sensor

2. to initialize the other 2 sensors use 

http://192.168.0.9/359/sensors_init.php

3. this will help you to switch to channel 1 channel[5]- mode (should be 1 for direct data path), channel[2]- switch to sensor 3, channel[1]- switch to sensor 2, channel[0]- switch to sensor 1): 

http://192.168.0.9/359/reg_write.php?adr=0x835&data=1

4. to test the DDR memory 

http://192.168.0.9/359/mem_test.php?row_adr=0x006&N=5

- parameters are start address and the number of rows to write and read

5.if you need to change phase of the clock to any sensor 

http://192.168.0.9/359/phases_adjust.php?rst=0&sphase=7&dcm=1&phase_shift=1&n=5
 rst         - reset all DCMs
 sphase[i]=1 - channel 'i' latches Vact/Hact on the FALLING edge of sclk0, sphase[i]=0 - RISING
 dcm         - number of DCM to use ('1','2','3' - same as channel numbers)  
 phase_shift - '1' - "+"-step, '0' - "-"-step
 n           - number of steps

6. to set frame size and some other things 

http://192.168.0.9/359/tests_for_96mhz.php?phase_shift=0&delay=0x000fffff&channel=33&pixes=2595&lines=1940

One of that things is memory controller initialization, registers are described in 

/elphel353-7.1/os/linux-2.6-tag--devboard-R2_10-4/arch/cris/arch-v32/drivers/elphel/x353.h

2008/09/19

set-up "353+359", x359.bit:

  • data from channel 0 after resync-ing to internal sclk0 goes to output which is synchronous to pclk at 353. Clock tree:
pclk-> 359's DCM -> sclk0)
  • other functionality is cut

I get good images, sometimes not. This happens after the power off and the cable from 359 to 353 is a bit deformed, then power on. Images do not break if the cable is deformed during camera work.

Conclusion: Misconfiguration?

1. 1 direct + 2 buffered images - done (added 5th cnannel to mcontr - simulated and tested as well). Trying to get difference between frames.

2008/04/25

1. make so that it will take less steps to get the frame from the sensor.

2008/04/22

1. Wrote a script for initializing all the sensors (they needed to set image frame size to 2596x1940 for the compressor to work properly) - sensors_init.php. It just copies parameters from sensor

2. Buffering one frame in DDR and switching between two channels (frame by frame, one buffered, one direct). But this needs to be tested more properly because there's a two black pixel line on the left side - that means Hact is latched two tacts earlier than data.

2008/04/13

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))?

2008/04/09

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.

2008/04/08

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.

2008/04/04

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

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. ...

2008/03/20

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

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).
