NvDlaSubmit: Error IOCTL failed (Cannot allocate memory)

[liufengwuhen]

I am running nvdla_runtime on nv_small on a fpga, but it has some error? Can some one tell me why?

is the opendla.ko been inserted into kernel before execute nvdla_runtime?

[liufengwuhen]

I have inserted the kernel module opendla.ko, the mistake has been solved. The new question is that the processor halt at "Exit: dla_initiate_processors status=0 "

[akioolin]

what test do you did?

btw, please check the content of /proc/interrupts. if nvdla issued any interrupt, there will be a record in /proc/interrupts

[liufengwuhen]

My command is "./nvdla_runtime --loadable CONV_D_L0_0_small_fbuf". I use ChipScope to collect the interrupt, but it has nothing. The record in /proc/interrupts also has nothing.

[akioolin]

I think the problem is caused by interrupt no send out to cpu. the nvdla interrupt had to be checked at first

[liufengwuhen]

Which bit should be checked?

[akioolin]

please check engine_isr.c

[liufengwuhen]

I use ChipScope to collect the interrupt, but it has nothing. The record in /proc/interrupts also has nothing. So the file engine_isr.c can not display anything.

[akioolin]

the root cause could be focus on nvdla's interrupt issue related design

[liufengwuhen]

Ok， We will check the related design and registers.

Hi, any update on this? I am facing a similar issue.

How do you solve the problem?(The first mentioned),just by insert opendla.ko? Hope to get your help,Thank U

Which bit should be checked?

Hello, did you solve the problem? I met the same issue.

[Yuxin-Yu]

Have anybody solve this problem ?
