PC port error'sPosted by Nobody/Anonymous on March 1, 2007 Hello, I'm a newbie to FreeRTOS, and I compiled it OK, and used a clean disk with FreeDOS (only to boot, without autoexec/config.sys) and running RTOSDEMO.exe compiled. I'm using an Compaq Armada E500 to test it, with LED's in Paralel Port, and pins 2-3 of COM1 connected. Without any code changes I get this errors: Maths task 4 failed. Maths task 3 failed. Maths task 4 failed. Maths task 3 failed. (etc) I change in FreeRTOSConfig.h the settings to: #define configTICK_RATE_HZ ( ( portTickType ) 200 ) #define configUSE_16_BIT_TICKS 0 I can get about 10 OK's, but then I start messing up, saying: Maths task 4 failed. Maths task count unchanged! Maths task count unchanged! (etc) Whats wrong? Thanks, jS RE: PC port error'sPosted by Nobody/Anonymous on March 2, 2007 From the docs: "When using Open Watcom, the NO87 environment variable must be defined". Have you type SET NO87=1 before running the exe? RE: PC port error'sPosted by Nobody/Anonymous on March 2, 2007 Hello, I've didn't checl that, where is that information? I've done it, and now it seams to be working ok, thanks. jS
