DS_DMA

Hi,

I ran the test against a Ubuntu 32-bit (4GB Memory) and some configurations must be wrong because right on start the test application doesn't read the TEST_CHECK and TEST_GENERATE block successfully. The BLOCK_IDs returned are x006F and x0200.
The test itself reported BLOCKs written but nothing received (log is attached).

I used all code from head revision and put together this configuration file using your expected output:

CntBuffer  8
CntBlockInBuffer  1
SizeBlockOfWords  262144
isCycle  1
isSystem  1
isAgreeMode  1
strmNo  1
isTest  2
FifoRdy  1
Cnt1  0
Cnt2  0
DataType  6
DataFix  1

AMBPEX50 process info output suggests no interrupt generated (as expected, since no results were obtained):

  Capability pointer: 0x40
  Capability ID: 0x7e034801
  Capability ID: 0x805805

I'll test with the 64-bit Ubuntu and report here.

Hi,
Thank you. There is error to access to registers. But DMA core runs correctly. It read a correct descriptor(FIFO_STATUS= a100).

No problems! I tested it on the 64-bit Ubuntu and the results were exactly the same as on 32-bit environment(except for 64-bit addressing).

But, interestingly, first I accidentally used the revision 9 driver and got erroneous data, but still data (interrupts were raised)!
I don`t know if this helps, but I`m attaching the log if you want to see.

New version tested. Test configuration: SP605 devkit + DELL-Studio-XPS-8100 + kubuntu-12.04.2-desktop-amd64.iso + SVN rev39 (SW).
Result - PCIE activity absent (based on program information).
Log file attached.

There is a error of read register. I try to set frequence to 125/2 = 62,5 MHz

Hi
New version: http://src.ds-dev.ru/files/sp605_lx45t_wishbone_2013_08_02_v1_0_build_02.zip
I set wb_clk to 32 MHz.
Please check it.
All test is complete.
All timing is complete.

Hi Dmitry,
I tested new FPGA design with SVN rev39 SW and have same results - PCIE activity absent (based on program information). I have same test hw configuration.
Please look log in attach.

GEN_CTRL=0x0000 - error;

read register - ok
write register - error
