RTOS/PRU-ICSS-INDUSTRIAL-SW: PRU-ICSS EtherCat Slave demo

Ryuuichi machida

Tool/software: TI-RTOS

Hello,

I would like you to confirm about below.

* I am trying to build PRU-ICSS-ethercat-slave 01.00.07.02.
At first, I performed "bat" file to create CCS project. There is no error.
After that, I import this project to CCS(version 9.1) and build this project.
Then, I observed following error.

Error : c:/ti/ccs910/ccs/tools/compiler/gcc-arm-none-eabi-6-2017-q1-update/bin/../lib/gcc/arm-none-eabi/6.3.1/../../../../arm-none-eabi/bin/ld.exe : region `SRAM_HI1' overflowed by xxxx bytes

So, I confirmed following file to check memory map.
"amic11x_onchip_mem_app.xdt"

To increase region of ".text" section, I changed length of "SRAM_HI1".(decrease region of ".bss".)
After that, region error of "SRAM_HI1" disappeared but region error of "SRAM_HI0" appeared.
So, I doubt that this project can be closed only internal memory.
Can you build without any error by using default memory map setting ?

Hi Ryuuichi,

You need to run dos2unix and apply the AM335x_PDK_thumb_mode.patch protocols\pdk_patches\05.01.00 and rebuild PDK, then build the EtherCAT project.

The patch file converting and applying procedure is similar as note here -

The procedure of rebuilding PDK is here - http://software-dl.ti.com/processor-sdk-rtos/esd/docs/05_01_00_11/rtos/Overview.html#rebuild-pdk

Regards,

Garrett

Hello Garrett-san,

Thank you for your reply.

I tried to run patch file. However, previous error remained. Here is my procedure.

--
* Download Windows Patch Utility from gnuwin32.sourceforge.net/.../patch-bin-zip.php

* Extract the zip file to the Windows PC.

* Launch DOS Command prompt and move to bin folder.

* Execute patch.exe with following syntax in windows environment

patch.exe -i C:\ti\PRU-ICSS-EtherCAT_Slave_01.00.07.02\protocols\pdk_patches\05.01.00\AM335x_PDK_thumb_mode.patch -d C:\ti\pdk_am335x_1_0_12 -p

(Question : I'm not sure how I should set number of "-p". I did not find any error by using above command, however, the reason which error remains may be related to this item.)

* move to C:\ti\pdk_am335x_1_0_12\packages

* Run "pdksetupenv.bat"

* Perform "gmake clean" and "gmake all".
--

I did not see any error in above procedure.
After that, I performed "projectCreate.bat" to create ethercat_slave project and import CCS.

Best Regards,

Ryuuichi,

There are two line changes only for the thumb mode if you open the patch file, so you can manually update the ti/build/makerules/rules_a8.mk file or check if it has been patched correctly.

Or try this command:

patch.exe -i C:\ti\PRU-ICSS-EtherCAT_Slave_01.00.07.02\protocols\pdk_patches\05.01.00\AM335x_PDK_thumb_mode.patch -d C:\ti\pdk_am335x_1_0_12\packages -p0
