open-usb-can-rev2.sch: HW and FW mismatch?
Hello
Fabio!
I want to use frash version of HW-design, but I see some mismatches between HW and FW:
- FW does not have a handler for LED_C functionality (probably POWER_ON?)
- FW doesnt handle INT-signal from MCP2515 (INT also exist in HW rev1, but floated end).
- FW not generate CAN_RESET-signal.
- Makefile FUSEs config: CLKO for clocking MCP2515 not enabled byCKOUT -fuse ("Clock output on PORTC7").
- Makefile FUSEs config: HWB jumper - exist in rev1 version, but HWBE-fuse (Hardware Boot Enable) is off. For what functionality exist HWB-jumper?
- TP3, TP4 - for which purposes? (FW dont have any settings for this uC-port pins)
Regards
Doka
DFU mode using
Hi Fabio!
What approach I should using for burning FW into ATmega in DFU-mode provided by proj?
As I know this chip already ships with pre-burned DFU-bootloader, and I would ask - what difference with code in "bootloader" folder?
Could I use with your bootloader vendor util like Atmel FLIP USB DFU?
Or maybe standard linux util lika dfu-util?
Thanks
kernel-module build troubles
firmware-sources nice and build perfectly fine,
but i have troubles with kernel-module build:
I have RHEL 6.5 64bit with kernel version 2.6.32-358.23.2.el6.x86_64
and I think that my system is not fully integrated SocketCAN.
By path /usr/src/kernels/2.6.32-358.23.2.el6.x86_64/include/linux/can necessary file led.h is absent.
And I have problem with others include files when building module (e.g. CAN_CTRLMODE_ONE_SHOT define) :
$ make KERNELDIR=/usr/src/kernels/2.6.32-358.23.2.el6.x86_64
make -C /usr/src/kernels/2.6.32-358.23.2.el6.x86_64 M=/home/idoka/open-usb-can/kernel-module modules

== Two ask: ==
- Which version of kernel you compiled the driver? What Linux distribution to use?
- Can I place new/missing header-files on existing kernel version or should I use only the version of the kernel for which writing a kernel module open-usb-can?
Fabio Thanks!
