RTOS/AM3359: PDK libraries

Cazaban Laurence

Part Number: AM3359

Tool/software: TI-RTOS

Hello Everyone !

I was an old user of industrial Sdk (from am335x_sysbios_ind_sdk_1.1.0.4 to sysbios_ind_sdk_02.01.03.02) .

As Texas will probably stop to support Industrial Sdk, I have decided to migrate to Processor Sdk with PRU_ICSS_Industrial.

So I have downloaded all the needed software:

bios_6_46_05_55
edma3_lld_2_12_04_28
ndk_2_25_01_11
pdk_am335x_1_0_7
xdctools_3_32_01_22_core
PRU-ICSS-EtherCAT_Slave_01.00.04.01
.......

I have an evaluation board iceV2 with arm3359.

I have followed all the explaination described in the PRU_ICSS_EtherCAT_User_Guide.pdf.

So I managed to generate the ethercat project I work with:

ethercat_slave_full (patched with beckoff sources)

Everything is all right: the project compile, load and run properly.

Now, I want to adapt this project to my custom board which is quite like the evaluation board but not really the same.

With the previous sdk , I had modified 3 librairies (libboard.a, board_support.a and sys_biois_driver.a) to adapt the pinmux, the gpio and all what was needed to be changed and I use these new librairies to run my own project based on ti project.

But now I don't manage to find what to modify ? Where are the librairies ? What function correspond to the old program ? What do I have to change ? Where is the pinmux ???????

I don't really manage to find what to do ?

Can you explain me what to do or if it exists a clear document that explain the way to do ? ( have already read "Porting Guide Industrial SDK to PRU-ICSS-Industrial & Processor SDK")

Really, it is very difficult to make the changes alone !

Thanks a lot

Thank you for the excellent comments.
Let me make some updates to the document to address the points you have made.

Hello David,

Sorry for not answering before but I has an accident and I wa away of the office for a pretty long time....

Now I'm back and I still try to convert my project based on SDK in the PDK way.

I have made lot of things and I must admit that it is quite hard to understand all the little détails.

I have still a issue I cant't mangae to resolve: how to configure ADC on my arm3359 using the new way with driver.

I think I have found a file in ti\pdk_am335x_1_0_7\packages\ti\csl\example\adc but I don't understand how to apply this to my case and how to retrieve the ti project using this file on my Platform.

Can you help me to do this ?

Thanks a lot,

Regards.

It seems that csl examples are only provided for AM57xx.
Is it possible to have an example with ADC for AM3359 ? I don't understand how to transform my previous code in the pdk way !
Thanks for your help

Hi

In the case AM335x and AM437x Starterware is maintained for legacy applications.
Building starterware has changed from the CCS GUI to a makefile .
For the AM335x and AM437x there are a couple of cases where you will see starterware providing the underpinning of CSL.
For the ADC code you may simply need to rebuild it within the new environment with just a few modifications.

If I put the code I have previously developed for adc, I have to include dal Library and after I have error for multiple definition because I already use i2c module int he cfg: var I2c = xdc.loadPackage('ti.drv.i2c');
I can't use dal Library and i2c module at the same time !
What can I do ?

Are you using a current EtherCAT project and adding the ADC code to that?

Hello David,

Yes, it is exactly what I'm doing because my project is based on TI project: ethercat_slave_full_AM335x_arm.

It is impossible to put libdal Library necessary to old adc and i2c module but I can't remove i2c module.

What can I do ?

Thanks

In fact I found how to do !
I only copy the files tsc_adc_ss.h and tsc_adc_ss.c in my project. So I don't need libdal anymore and everything is ok !
Thanks a lot for your help
