LAUNCHXL-F28377S: error #10234-D: unresolved symbols remain

for example, where is the entity of the ClkCfgRegs ?
There is no information about entity for all of above...

Hi Takano-san,

First of all, which example project is this? From where did you import and which CCS version do you use currently?

Hi Iyer-san,

At first I would like to write appreciate to you, because of this theme is difficult to explain, I think.

I started from no example code, from a scratch. Other engineer started to code spi communication with a special configuration (multiple spis for single protocol). I used his code and embeded into my code using, spi, pwm, timer with interrupt, and etc. After that now I meet such the error, and now I can not remake (reproduce) same error because of I changed "--preinclude", and did not take memo for it so I can not make previous setting in now.
After removed "--preinclude", I meet following errors in now;

"C:\ti\controlSUITE\device_support\F2837xS\v210\F2837xS_headers\include\F2837xS_can.h", line 530: error #2638: The alignment of an array element is greater than the element size

I have a little bit confusion, why the removing --preinclude made such the errrors...

In order to solve current error, if you need other information, I will present here as possible.

Thanks and Regards,
Takano

Now I reproduced same error of ;

CCS version is Version: 7.1.0.00016

Regarding bellow entities, F2837xS_Gpio.c describes the entities, not a central file but it is distributed in the directory.
_GPIO_SetupPinMux ./init.obj
_GPIO_SetupPinOptions ./init.obj
_GPIO_WritePin ./ctrl_init_err.obj

I think that checking sample code's files in the project have or not have such the entity portion is required.
So, I need information about which file and where is the directory above items have each entity.
Does anyone have such the information, I believe TI member have such information because of management of source code.

However, I can not image how link between the fie and source code in sample code, for example, blinky example have F2837xS_Gpio.c but I do not understand how to link between source code and the file . Is it based on a linking option in property?

Hi,

If showing a map between the function made the linking error and its location or file name, then how to find out such the map?
If difficult to find, how to solve my situation?

Anyway how to link if I found a file?

Takano
