FF5.0: CPU load calculation wrong after first word is compiled?

[Holger]

Hi, I've found some strange behaviour:

Right after power the CPU load calculation on FF 5.0 is in the low %-age, and it remains there. If a LED is connected as load indicator it stays rather dark as well.

However, once the first word is compiled into the flash both the LED and the CPU load calculation via "load" switch between dark/bright or low/high precentage with a cycle time for a minute or so. Once the system is reset the load remains in the low %-age again. To be more precise: the LED is bright for a minute, dark for a minute, bright... with a corrsponding CPU load polled via the "load" command, ex. 96 vs. 3.

CPU: PIC24FJ64GA002

Config:

[...]

.equ IDLE_MODE, 1

.equ CPU_LOAD_TRIS, TRISB
.equ CPU_LOAD_PORT, LATB
.equ CPU_LOAD_BIT, 15
.equ CPU_LOAD_LED_POLARITY, 1 ; 0 = low on port turns on led, 1 = high on port turns on led

; Define the startup delay for turnkey words. Milliseconds
.equ TURNKEY_DELAY, 2000 ; milliseconds

Your config file looks old. That could be the problem
Start again with the latest code and config files from GIT.

At least it works on my pic24hj128.

Ok, I will check tomorrow

Rats - my bash shell script linked to the old forth version.

FF5.0 works.
