66AK2H06: ARM has slow read speed to PCIE memory

Hi Shankari,

I try to use involve EDMA in the Linux c program application.

it shows CSL_edma3Init is undefined, how do i solve this? Here is what i include.

#include <ti/csl/csl_edma3.h>
#include <ti/csl/csl_edma3Aux.h>

thank you,

Yao-Ting

Yao,

Check whether there are macros to enable the particular SOC

For example,

__ARM_ARCH_7A__   --- For ARM

SOC_K2G   -- for K2G

SOC_K2H   -- for K2H

_TMS320C6X -- for DSP

#if defined(EDMA) || defined(UDMA)

etc....

Hi Shankari,

I found there are two examples for ARM applications about PCIE and EDMA.

one is PCIE_K2H_wSocFile_armExampleProject

The other is PCIE_K2H_wSocLib_amExampleProject

what is the difference?

thank you,

Yao-Ting

Yao,

As the name of the project implies, one is the "LIb"  and the other is the actual example project.

This Lib will be serving as a library to the other.

Let me look at it little more closer and get back.

Yao,

The source files used seems to be the same. The configuration files and binaries are different.

1. But the ".cfg has a difference in enabling the SOC type.

     /* Enable only if soc-specific library should be used */
          Pcie.Settings.socType = socType; ----> This line is disabled / commented out in "pcie_sample_wSoCFile.cfg" but enabled in "pcie_sample_wSoCLib.cfg"

2. As well, the size of the binaries differ.

Hi Shankari,

i can open the project and compile under Windows CCS.

but if I copy files to Linux environments and use ti tool chain to compile, it shows ti/sdo/edma3/drv/sample/bios6_edma3_drv_sample.h : No such file or directory.

Usually, how people solve such issue if CCS compiles work but fails to compile under Linux tool chain.

Thank you.

Yao-Ting,

Migrating from one operating system (SYSBIOS )  to another (Linux)  is always a challenging task.

As the TI offered environment is SYSBIOS, if customer wants to compile under Linux, they have to adapt themselves.

 Thanks for understanding. Let us close this thread.

Hi Shankari,

Sorry, my previous statement is confusing. I want to compile the code but this code is still running in 66K2H02, ARM side (Linux OS).

now my application is using arm-linux-gnueabihf-gcc and arm-linux-gnueabihf and armv7at2hf-neon-linux-gnueabi. They works.

I think they are download from Ti website.

but now, I have issue if I try to compile EDMA module.
