Re: [Xenomai-core] Bug - Can 2 devices.
Hello Worlfgang, Thank you for your help, I discovered that the problem was in my SOCK application in user space, not in the kernel. You were very thoughtful, thank you. Rodolfo Romao.

Re: [Xenomai-core] Bug - Can 2 devices.
Hello, On 07/28/2010 08:15 PM, Rodolfo Oliveira wrote: Hello friends, I am developing a project and I'm using two CAN. The Can one is working, but the CAN 2 is not, i 'm recompile the kernel enabled the can 2, but I can not make it work. Scenario: - I can print the frames in CAN 2, I get in the kernel log (dmesg) and the frames are correct. - CAN 2 works normally if I disable the CAN 1 and recompile the kernel. Problem: In the rtcan_raw.c in function void rtcan_rcv (struct rtcan_device * dev, struct rtcan_skb * skb) there is a verification while (recv_listener! = NULL) and the problem is that the variable recv_listener is equal to NULL . This variable comes from the function static int rtcan_mscan_interrupt (rtdm_irq_t irq_handle *) (which is on file rtcan_mscan.c) this function passes a struct as a parameter dev = (struct rtcan_device *) rtdm_irq_get_arg (irq_handle, void) to rtcan_rcv and it contains the recv_listener = dev- recv_list. Soon the CAN2 is working but there are some configuration issues in this code. Can anyone help me with this problem? Are you speaking about the MSCAN driver for the MPC5200? The routing of the second CAN port is configurable. Maybe it's not using the right I/O pins. What CPU and Linux version are you using?

Hello, please do not drop the CC to the mailing list. On 07/29/2010 04:33 PM, Rodolfo Oliveira wrote: Sure, the answers follow: 1 - What version of Xenomai do you use? A: Xenomai 2.2.91 Puh, that's very old code and I can't identify the MSCAN sources for that version. Could you please send your mscan.c?

Hello, On 07/29/2010 10:37 PM, Rodolfo Oliveira wrote: I copied the command # rtcanrecv 0xFFF-e for my microcontroller and I can not run it, this appeared the following message / opt/denx/xenomai_2_2_91/src/utils/can: No such file or directory. Microcontroller shipped with Linux 2.4 with Xenomai is cross compiled on Linux on my desktop computer, so he will not find the directory that the rtcanrecv are trying to access. Is there another way to do? I usually mount the root filesystem of the ELDK via NFS and install the Xenomai libraries and utilities into it. CONFIG_XENO_DRIVERS_CAN_MAX_DEVICES=4 OK, I checked your sources and realized, that you use a very very early version of RT-Socket-CAN. Any chance to switch to a more recent version of Xenomai 2.3? If not, please check the related commits of the xenomai-2.3 or xenomai-2.4 git repositories. I spotted a few fixes which may help.
