Hi,
Was wondering if anyone has tried using the "dmatest" of Xilinx Opensource Linux bundled with the Microzed. Though the boot process indicates:
VFP support v0.3: implementor 41 architecture 3 part 30 variant 9 rev 4
Registering SWP/SWPB emulation handler
dmatest: Started 1 threads using dma0chan0
dmatest: Started 1 threads using dma0chan1
dmatest: Started 1 threads using dma0chan2
dmatest: Started 1 threads using dma0chan3
dmatest: Started 1 threads using dma0chan4
dmatest: Started 1 threads using dma0chan5
dmatest: Started 1 threads using dma0chan6
dmatest: Started 1 threads using dma0chan7
drivers/rtc/hctosys.c: unable to open rtc device (rtc0)
mmc0: new high speed SDHC card at address 1234
mmcblk0: mmc0:1234 SA04G 3.63 GiB
mmcblk0: p1
IP-Config: Guessing netmask 255.255.255.0
IP-Config: Complete:
However, when trying to run the dmatest, as posted on
https://www.kernel.org/doc/Documentation/dmatest.txt
at the "zync"prompt, I get:
zynq> dmatest.channel=dma0chan0 dmatest.timeout=2000 dmatest.iteration
s=1 dmatest.run=1
-/bin/ash: dmatest.channel=dma0chan0: not found
zynq>
Or trying it as a module :
zync> modprobe dmatest channel=dma0chan0 timeout=2000 iterations=1 run=1
zynq> modprobe dmatest channel=dma0chan0 timeout=2000 iterations=1 run
=1
modprobe: chdir(3.8.0-xilinx): No such file or directory
Would appreciate if anyone can share how to run the dmatest on Microzed.
Thanks
