AM2634: SysCf with Mcal driver

Panda Bear

Part Number: AM2634
Other Parts Discussed in Thread: SYSCONFIG

Hi,

I try to integrate some of the syscfg drivers into my mcal project. Therefore I want to change some line of codes in the generated ti_drivers_open_close.c file. When I always built the project; all changes are away and the generated .c file is back to its first version.

So my question is; is it possible to change it and how? If no; how can I integrate the syscfg drivers with less effort (The driver from SysCfg is I2C)?

Thank in advance and best regards

Hi Panda Bear

FIrstly, it is not recommended to use sysconfig or SDK drivers directly into MCAL. The reason being the SDK drivers has dependencies on lot of OS calls and stuff like semaphores etc., which is currently not implemnted in the MCAL drivers, so please integrate the drivers at your own risk.

Panda Bear said:
is it possible to change it and how?

Yes, I can surely help on this and it's possible. But the only way to do this is not use CCS to re-build the project after your changes because it triggers a makefile build which cleans the sysconfig files and re-generates them. To override this, go to the workspace where your project is present and go into the Debug/ folder where you'll find a makefile like this, then open a cmd in this folder and run "gmake -s all" this will compile the changed file only and gives you the output.

I have edited the ti_dpl_config.c file and you could see that only that file is compiled. Hope this helps.

Hi Kowshik,

We have integrate some of your mcal driver into our project amd it works vell. Now we need to integrate a cdd driver which is I2C. When i run the I2C driver in Polling mode then it works well; this means for me semaphore functions are working well. but when I try to interrupt mode, i got the following trap:

Could you discuss internally and give us any suggestions?

Hi Panda Bear

Integrating freeRtos to the MCAL drivers is not straight forward as we expect. One of the things that I recommend checking is how the interrupt registration is being done? It should be done through the Hwip module instead of the existing vim( ) module. This makes sure the interrupt and handlers are properly registered.

Can you change this implementation? Also, can I know what's the linker you're using? there are some changes required to the MCAL's linker file as the SDK code is coming into the picture and start by making the following changes

Add the above section at the bottom of the linker file

change the BSS linker symbols as shown

change the intvecs to .vectors to comply the SDK's notation.

Please increase the size of the SVC stack to 4096 incase you're enabling the interrupt nesting as this can cause stack overflow issues.

Hope this helps

we have already integrated the freertos in our project and it works fine. for the interrupt we have used the vim and this is called only once in our project.

the changes which are made in i2c sys drivers are

and vimEnableInterrupt and vimDisableInterrupt is used in transfer function, where needed.

finally my linker script is shown like this:

/* This is the stack that is used by code running within main()
* In case of NORTOS,
* - This means all the code outside of ISR uses this stack
* In case of FreeRTOS
* - This means all the code until vTaskStartScheduler() is called in main()
* uses this stack.
* - After vTaskStartScheduler() each task created in FreeRTOS has its own stack
*/

/* This is the size of stack when R5 is in IRQ mode
* In NORTOS,

* - This is the stack used by ISRs registered as type IRQ
* In FreeRTOS,
* - Here interrupt nesting is enabled
* - This is stack that is used initally when a IRQ is received
* - But then the mode is switched to SVC mode and SVC stack is used for all user ISR callbacks
* - Hence in FreeRTOS, IRQ stack size is less and SVC stack size is more
*/
__IRQ_STACK_SIZE = 256;

Hi Panda Bear

The linker seems to be wrong, it's looking like you simply appended the MCAL's linker to the SDK's linker. This is not recommended because many of the parameters might get overwrittern for example like entry points, stack namings etc.,

Please use the below linker command as a reference.

Sorry Kowshik

I only use the first one also this:

SECTIONS
{
/* This has the R5F entry point and vector table, this MUST be at 0x0 */
.vectors:{} palign(8) > R5F_VECS

/* This is rest of initialized data. This can be placed in DDR if DDR is available and needed */
GROUP {

.data: {} palign(8) /* This is where initialized globals and static go */
} > OCRAM

MEMORY
{
R5F_VECS : ORIGIN = 0x00000000 , LENGTH = 0x00000040
R5F_TCMA : ORIGIN = 0x00000040 , LENGTH = 0x00007FC0
R5F_TCMB : ORIGIN = 0x00080000 , LENGTH = 0x00008000

Hi Panda Bear

I guess it's still not correct because you're using the SDK's linker file for the MCAL code which causes compatibility issues. Please use the linker file I attached in my previous reply as a reference and build on top of it please.

Thanks,
G Kowshik

HI Kowshik

Can you do it for me? I think this is out of my knowledge. so I can copy back to my project. Or Can we do a live session?

This is already inside the linker. and the size SVC is also already 4096

Hi Panda Bear,

The linker file you're showing is from the SDK, please use the below attached linker once (this has the portability issues fixed to an extent and lets you initialize the vector tables etc., correctly)
