: Ataya P Date : 24 May 2007 Introduction After 3 days that I couldn't sleep. Finally ,I could porting microC OS II into m16c OAKS board successfully.It's not too hard but still using more patient and use some trick to made it working.Most of functions are working fine. Anyway I still can not use of interrupt function.May be next time I will write more about this after I could find the point of problem.(^-^)/" Before cooking Ok.First of all. We need some ingredients for making this project work. Here is a list - Hardware PC : my PC is desknote VIA cpu 500 MHz RAM 256MByte Window 2000 --little bit slow. Hardware : M16C OAKS board with LCD support board also. - Software HEW version 4.2 up with m16c C compiler and flash download program. Making time I just download porting file for M16C Renesas from uC/OS-II official website.Anyway , Some files has been lost or not include in the zip packet.So, I download another porting file of M16C LCD project from the same website and just copy the lost file form M16C LCD project to normal M16C project directory.(Please look at AN-1019.pdf for more detail)  Pic 1 : uC/OS-II project file list From picture above.You need to include all files on the list.Anyway, I didn't use LCD from the original LCD porting project.So, I just include my own M16C LCD api that I made for a long time ago(Not in galaxy far far away (-_-)) into the project. After you prepared all files already.Just open HEW and choose new workspace.select M16C/R8 type mpu and never forget to select startup file option for USER (because you will use your own startup file .Right ?) After finish generate new workspace.Open Build-> M16C Renasas Standard toolchain and Include all directory about this project into include file directory and just click on Link tab. Select Relocatetable file and add your startup file in to this dialog box.  Pic 2 : Select your own startup file
Finally,We already to compile uC/OS-II
project.So,I try to compiled it.It compiled without problem but when I
flashed this one on my board. ......Nothing moving !!
After thinking about one day and night.I figured out that
somethings must be wrong for startup file. So,I just copy address value
from another M16C project into uC/OS-II startup file. It's working
!!!(Well,not for interrupt yet.Sorry)
I try to use Semaphore,Mailbox and Message Queue. It 's working fine but for user interrupt it still something that I could not understand yet.May be if I have some time.I will fix this problem.Ok.Hoping you enjoy this article.See ya next time (^_^)
