some questions about InstaSPIN-motion

Other Parts Discussed in Thread: MOTORWARE

now I finish all the labs, but some questions confused me .

1)  How to download the program into flash memory ? T I write ：#define flash , but CCS compile failed . 

2) I add SCI receive interttupt function in proj_lab13e.c , and when I send a character to MCU , The CCS will report errors .

3) About question 2 , how CCS compiler communicate with MCU ?  by SCI ? no.  by what ?

4) lab13e say gMotorVars.MaxJerk_krpmps2 can reach 400.0 , but  I can reach 120.0 only , why ?

so can anyone  give me a hand ?

    1. To download the projects into the FLASH you need to change the build configuration of the project.  Right click on the project select Build COnfigurations -> Set Active and select Flash.  In addition to the preprocessor define FLASH, there are some additional files that are included and a new linker file.

    2. I'll have to let the TI experts comment about this one.

    3. CCS compiler communicates with the MCU over JTAG.

    4. Are you configuring gMotorVars.MaxJerk_krpmps2 to be an IQ20 variable?

    Hi Adam,

      Thanks for the reply.

      1. I selected Flash, should I define FLASH?  Can you tell me more informations about the additional files that need to be included and the new linker file.   

     2.I modifed my code , and the CCS compiler  shows normal , but  the program can not step into sci receive interrupt  fuction, I will check my code again.

    3.when I cut the JTAG , the program is stoped , so I need to download the program into FLASH memory .

    there are several posts on the front page about SCI and SPI communication. Note that most of these peripherals are NOT set-up / enabled in the example projects. We only set-up what is required for that specific example.

    You need to follow the examples of peripherals that are enabled and the HAL tutorial

    Stefan,

    When you have selected the Flash target, it should already have defined FLASH for you.

    It pulls in these files:

    CodeStartBranch.asm - This branches into the c_init00 function

    memCopy.c - This will copy select functions from FLASH into the RAM

    F28069M.cmd - This is a new linker file that will load code into the FLASH instead of RAM
