I am using the 7.05P versiuon of the OS, with uC/OS-II Your behavior is the exact problem I am having. Reflash (works for sure), or remove the boared and...
Some extra data - when the device faiols to boot, simngle stepping through the code, reveals it is trying to start execution at the wrong part of the flash (or...
I thought to check something, and found that if I disconnect the battery, and allow the voltage to drop below about 1V (discharge my on board caps), or I short...
... Hmmmm... That's a worry. The only boards I've had exhibit this problem have been using DC 6.57R2 All of my new stuff is using DC 7.05 premier, and I...
Hi RS7, ... As I mentioned in my previous message, I can't get a debugger into my board, so I've got to wait until my TSOP adapter arrives next week to read...

I will let you know if I have anything as well - I have been going back and forth with tech support at Z-world as well (David Terra). He made a suggestion to...
Hi All, I am in the middle of re-writing the I2C routine to assembly (I need to speed it up) and I think I have everything working like it is supposed to but...
I think I answered my own question. It was the MAX518 chip's ACK signal that holds the data line low until it sees another clock pulse. I'm pretty sure that...
I am trying to edit premain, in order to add an ipset 3 at the start, and then execute an ipres before main is called. I want to see if this will solve my boot...
Hi Folks, I've run into this problem at the moment. Let me describe briefly what's happening. I'm pumping much data out of port A, under the guidance of a...
You could always try using the ".map" file to get the address of the routine in question and then use the "disassemble at address" function. Regards Phil...
... Hmm, that seems to work, thanks! (Also, the disassemble at cursor thing works too). Great, now to find out why my application code doesn't go :-) Thanks...
... Hi David, Can't answer your question about the ASM listing as there's none that I know of, but I also use COM-A in real life. How I handle development...
... Hi David, Something to keep in mind, I have noticed that the STDIO as used by the debugger, puts a heck of a load on the system if you start using it. If...
Hello I am using timerB clocked by timer A and the numbers I gave the two constants are: #define TIMER_A_VAL 199 // Timer A divides by N+1 #define TIMER_B_VAL...

I take it the original architecture of the z80 family is used on the rabbit 2000 parts? Looking at the instruction set clock cycles, most instructions require...
Richard Solving a problem by explaining it to someone else works amazingly often. It's like you use a different part of your brain and WHAM the solution just ...
Remember though that the PICs divide the external clock by eight - so in effect theyu take 4 actual clock cycles to perform each instruction. I used a 17c756...
Untill today I worked with AVR, 8051, Motorola and PIC. (If I go back a little bit more, so there is also the Z80).
For a new project the Rabbit seems to be...
... My current project is using PIC18C452 running with a 10MHz Oscillator using the internal PLL to obtain 40MHz which results in a 10MHz internal clock. That...
This question is valid for any CPU system that stores its code external to the CPU. There's nothing that prevents someone from desoldering your flash on any...
