Other Parts Discussed in Thread: SYSBIOS, PROFIBUS

Hi all,

I have an ice board and I want to use and try ADC channel with Sys/Bios.

My initial conditions: CCSv5; am335x_sysbios_ind_sdk_1.1.0.4; xdctools_3_25_05_94

I read in this post that a package named InOut_ICE can help me:

e2e.ti.com/.../278454.aspx.

If I import it in CCS, an error appear in the main file: the compiler don't find the "am335x_indcomm_startup.h"

If I search it with explorer it find in the old directory: am335x_sysbios_ind_sdk_1.1.0.1, but this file doesn't exist in the am335x_sysbios_ind_sdk_1.1.0.4 directory.

My question: Is it possible to redefine IA_SDK_HOME to force CCS to use the old SDK (SDK 1.0.1) instead of the SDK 1.0.4 version ?

If not possible, I shall replace the IA_SDK_HOME by a relative path...

Suggestions ?

Moving this to the SYS/BIOS forum.

Hello,

There has been changes from ISDK 1.1.0.1 to 1.1.0.3 . Please find the details here.

I would suggest to either use 1.1.0.1(which is quite old now) or make the required changes in "InOut_ICE"

Regards,
Vinesh

Hello Vinesh and thank you for your answer

Yesterday, In the first one I changed the paths in the ARM Compiler and ARM LINKER:

I replaced the windows variable IA_SDK_HOME by the full path referenced the ISDK 1.1.0.1

I modified also the structure array SYS_MMU_ENTRY applMmuEntries[]:

For every menber: {(void*)0x48300000,(unsigned int)0x48300000,0,0}, become {(void*)0x48300000,0},

I have disabled the IPC in the RSTC window.

Now, it's ok, the programm is running....

Regards

I have modified the main file to compil it with the SDK version 1.1.0.4.

0081.main.c

Have a nice day.

Hi Jean,
I tried running Inout_ICE and I also made changes as you mentioned in your post. But I am working with ICE v2, and I am not able to get anything printed on the terminal. Is there any extra change to be made in the program?

Rohan

Hi,

There are differences between ICEv1 and ICEv2. Is the pinmuxes configured properly?

To get things starting, the UART instance is different for ICEv2. From the uart_echo example -

if(AM335X_BOARD_TYPE_ICE == boardType)
{
uartInstance = 5;
}else if(AM335X_BOARD_TYPE_IDK == boardType)
{
uartInstance = 3;
}
else if( AM335X_BOARD_TYPE_ICE_V2 == boardType)
{
uartInstance = 3;
}

Regards,
Vinesh

Hi Vinesh,

I am able to print messages on terminal using UART console so i guess uart configuaration is fine. I used the profibus_slave SDKMMUInit for mux, without which I am not able to print also. According to previous posts, I tried adding hwi for adc but still no results. I am attaching rar file of my whole project below. Hope it could be of any help in solving the problem. The project is built using sysbios 2.1.1.2, bios 6.45, CCS v6.1.1.1.

Regards

Hi,

I'm a little confused. The application you shared doesn't look like anything that was discussed in the thread(application based on 1.1.0.4). There are a lot of changes in SDK 2.1.1.2, and Starterware being the major change.

If you are trying a new application based on Starterware(from 2.1.1.2), please post a separate thread in the Starterware forum.

Taking a quick glance at your application, I still see no pinmux configuration done.

Regards,
Vinesh

Hi Vinesh,
In CCS platform, the project is running fine but when I tried to convert it to RTSC platform by modifying profibus_slave example, I could successfully build the project but while running it is getting stuck at TSCADCenable() function. If we are including in RTSC platform is there extra
content other than this to be added?

Rohan

Hi,

One thing I noticed, although you have enabled ISR in main, you are reusing the INTC module from starterware.

Hi,
Thanks Vinesh, that was the problem. Now I could run the program successfully, after modifying the ISR and using INTC only once.
