Hi, I'm attempting to compile the RTX51 CAN Example Program for the Infineon C515C example from the keil website without much success. I'm using the PK51 with full RTOS. I import the uVision version 1 project following the instructions on importing files from uVision version1. I changed the TARGET_PROC to 515, as this is the chip I hope to use. I've checked the environment, changing the frequency to 16Mhz for the CAN timing calculations. The project compiles without error, but unfortunately produces linker errors.

I too have been experiencing difficulty with the CAN bus and would be appreciative of any answers to this question
First of all uncheck "code banking" box. Second, you're obviously using V7.0 RTX51 kernel and CAN examples were written for V5.0 V7.0 introduced RTX_PAGE_OUT_REG variable, to allow cores (like Cygnal) which use other registers for paged XRAM access instead of P2. So, you'll have to add this lines: PUBLIC ?RTX_PAGE_OUT_REG ?RTX_PAGE_OUT_REG DATA 0A0H to your RTXCONFA51.INC file Locate this part: ELSEIF (?RTX_CPU_TYPE = 21) and just add those two lines and recompile. regards Dejan P.S. if you have troubles, contact me here: dilogic@zg.htnet.hr - I have A LOT of experience using RTX51 and CAN...
Just noticed a typo: when I said RTXCONFA51.INC it should actually be RTXCONF51.A51 regards Dejan
Thanx Dejan, It works!!!!!! :0) And someone who knows what they are talking about...brillaint. I noticed that when you simulate it appears to get stuck, but when you transfer it to the dev board it runs fine. Thanx a lot. Carol-Anne
Hi I've been playing around with the RTX51 CAN Example Program for the Infineon C515C. I've hit a problem though, my send module increments the LEDs of the Phytec Development board, with the transmit pin flashing on and off. However as soon as I turn my receive module on, my transmit module stops transmitting. If I reset the two boards the transmit board still refuses to transmit. In the code I have set
SENDER to 1
SENDER to 0
I suggest that you try demo program located in KEIL\C51\CAN\C515C folder. That one works for sure. If you cannot locate it, email me and I'll send it to you. regards Dejan ( dilogic@zg.htnet.hr )
