mscan_loopb does not work #276

Closed mad-jsanjuan closed 1 year ago

mad-jsanjuan commented 1 year ago

The mscan_loopb program does not seem to work on a CAN interface:

https://github.com/MEN-Mikro-Elektronik/13Z015-06/blob/master/DRIVERS/MDIS_LL/MSCAN/TOOLS/MSCAN_LOOPB/

$ sudo modprobe -r men_ll_z15
$ sudo modprobe men_ll_z15
$ sudo mscan_loopb -t=a can_1

This was detected using the IP core z029 on a BL51 box pc.

Here is the dmesg output when running the test program with all Debug enabled from the system.desc for a CAN ip core.

I talked with the FPGA developer of the 16Z029_MSCAN IP core.

Please try the following: 1) Test with 125kbit bitrate: $ sudo mscan_loopb -t=a can_1 -b=4 2) If it 1) doesn't work, provide us register dumps of the Z029 IP core a) after power-up, before the men_ll_z15 is loaded b) after the men_ll_z15 is loaded c) after mscan_loopb execution

Hi Jorge,

I answer via mail because we are currently in island mode 😉

According our FPGA developer, the register dumps lock reasonable. Please investigate if the interrupts from FPGA to Linux works. You can check if Linux gets some interrupts via command line.

Or try to trigger some interrupts at one of the GPIO units which shares the same IRQ line:

I found this Errata on the BL51 box pc manual (https://www.duagon.com/products/details/BL51E/#doc) :

Is it possible this example program was never meant to run on this BL51?

mad-jrodriguez commented 1 year ago

Hi all,

I have tested mscan_loopb executable in CAN buses within F215 and G215 boards and they work as expected so the issue detected in BL51E seems to be related with the Errata @mad-jsanjuan found yesterday.

CAN_7 G215

men@men-F027:~$ sudo mscan_loopb -t=a can_7
=== Performing test a: Basic Tx/Rx                                 (Run 1/1) ===

=== Performing test a: Basic Tx/Rx                                 (Run 1/1) ===

Good work! I wasn't aware of the mentioned BL51 errata and the known CAN issues. I think you are right and I close this issue now.
