Can I use mxc_sdma_mem_test.c for i.MX6Q?

[hiromichimatsum]

Dear all,

I am developing the pci device driver using sdma in i.MX6Q on Sabrelite.

The aim of the driver is to transfer the memory to pci space.

I think that I use the test code, mxc_sdma_mem_test.c in imx-test.

I tried to build the test code, but I couldn't build the test code.

I attached the "error.log".

Can I use mxc_sdma_mem_test.c for i.MX6Q?

If I can use the code, could you please show me how to build the code?

If I can't, could you please show me the other sample code for sdma?

My environments is as follows:

     Target: Sabrelite(i.MX6Q)

     Build Environments: Yocto (Dora)

Change the Makefile for build:

     imx-test-3.10.9-1.0.0/module_test/Makefile

     ----------------------------------------------------------------

     *** 15,23 ****

       ifeq ($(CONFIG_MXC_SECURITY_RNG),y)

       module_list-y += sahara_test_driver.o

       endif

     ! ifeq ($(CONFIG_MXC_SDMA_API),y)

       module_list-y += mxc_sdma_mem_test.o

     ! endif

       ifeq ($(CONFIG_FB_MXC_EINK_PANEL),y)

       module_list-y += epdc_test_driver.o

       endif

     --- 15,23 ----

       ifeq ($(CONFIG_MXC_SECURITY_RNG),y)

       module_list-y += sahara_test_driver.o

       endif

     ! #ifeq ($(CONFIG_MXC_SDMA_API),y)

       module_list-y += mxc_sdma_mem_test.o

     ! #endif

       ifeq ($(CONFIG_FB_MXC_EINK_PANEL),y)

       module_list-y += epdc_test_driver.o

       endif

Best regards,

Hi Hiromichi

mxc_sdma_mem_test.c can be used and

it is easily compiled in ltib

L3.0.35_4.1.0_ER_SOURCE_BSP : i.MX 6Quad, i.MX 6Dual, i.MX 6DualLite, i.MX 6Solo and i.MX 6Sololite Linux BSP Source Code Files.

For Yocto buld problems I would suggest to start with link

below and ask yocto experts (DaianeAngolini, LeonardoSandovalGonzalez,OtavioSalvador)

Freescale Yocto Project main page

Regarding SDMA, there are SDK SDMA examples

i.MX 6Series Platform SDK : Bare-metal SDK for the i.MX 6 series, including reusable drivers and tests for many peripherals

Best regards

Hi chip,

I tried to build in ltib, but I couldn't build mxc_sdma_mem_test.c.

The errors were almost same as before.

I attached the error log for reference.

If I want to use mxc_sdma_mem_test.c in latest build environment, I may need to change it.

For example, "mxc_dma_requestbuf_t" structure used in the test code isn't implemented in the kernel.

I will try the other way.

Best regards,

Hiromichi

Hi all,

I made a big mistake!

I should use "mxc_sdma_memcopy_test.c", not "mxc_sdma_mem_test.c".

When I use the code, I get succeed to build.

And, I can run my sdma test application in user space without any problems.

Thanks for your cooperations.

Best regards,

Hiromichi

hello,

I'm sure that you can use mxc_sdma_mem_test.c, but you need to configure your compile environment!
