How to use CAN_LDD with interrupt service ?

hanchengyang — Wed, 25 Mar 2015 10:35:41 GMT

I have used KE06Z, and with MQX Lite, while I used CAN_LDD with interrupt service active there are several errors as below:

and I verified structure CAN1_TDeviceData, and there is no member called 'SavedBusOffISRSettings', and I have tried deleted these lines and compile passed, but cannot go into ISR.

these codes are in 'LDD_TDeviceData* CAN1_Init(LDD_TUserData *UserDataPtr)'

Hello,

I have tried to reproduce the error in CW MCU 10.6.3 and KDS 2.0.0 but the generated code can be compiled without any error. I have also checked that the CAN_LDD driver contain the same code you have mentioned:

/* Allocate interrupt vectors */

/* {MQXLite RTOS Adapter} Save old and set new interrupt vector (function handler and ISR parameter) */

/* Note: Exception handler for interrupt is not saved, because it is not modified */

DeviceDataPrv->SavedBusOffISRSettings.isrData = _int_get_isr_data(LDD_ivIndex_INT_MSCAN_TX);

. . .

But this code can be compiled without errors.

Could you send me the project or the Processor Expert project configuration (Exported Component Settings - .peb file) for analysis, please?

Please, send me also the version of the Processor Expert product you are using (e.g. CW MCU 10.6.3, KDS 2.0.0).

Best Regards,

Hello

Thanks for your intention, but i have already solve the problem, by adding

two elements into LDD CAN structure in can.h.

Hello,

I have checked our database of issues and this is known issue of CAN_LDD component driver. We have fixed the issue and there is available a hot fix for KDS 2.0.0 and CW MCU 10.6.x. See attached hot fix packages.

Best Regards,

MArek,

On KDS 3.0, this issue was solved or need to fix manually too?

Hello Carlos,

The issue has been fixed in the KDS 3.0.0 (PEx for Kinetis 3.0.0). You can see the issue PEXMCU-1276 in the Revision History of the KDS_3.0.0\eclipse\ProcessorExpert\PEx_for_Kinetis_3.0.0_Release_Notes.pdf:

PEXMCU-1276 - Fixed defect: The CAN_LDD component code doesn’t build when using with MQX-Lite. The structure <Name>_TDeviceData in the CAN_LDD header file is missing members, like SavedBusOffISRSettings.

Best Regards,
