i.mx6 on qsabresd and SJA1000 CAN Controller

[francpalm]

Hi, I need to connect and mange one or two SJA1000 CAN Controller to EIM bus of my qsabresd board.

Someone can help me for HW point of view (DataAddress pin, Voltage compatibility, Interrupt, Chip Select, etc) and for SW point of view (Driver, Kernel, Memory Address location, etc.) ?

Thanks.

Thanks for creating this new thread. I hope someone else can help you in HW perspective.

Was sja1000.c enough for your software update?

[francpalm]

No, unfortunately is not enough!

I need to understand how to configure the EIM bus to use it as multiplexed (data/address) bus, how to configure the chip select and the interrupt to and from the sja1000 and so on!

The best would be to have an application example or a manual or an howto!

Anyway many thanks!

mx6q has built-in CAN controller. Why don't you just use them instead of external CAN controller?

[francpalm]

Because I need 4 or 6 CAN Channels! Is an application for a special vehicle!

Understood.

sja1000 is supported in the kernel: drivers/net/can/sja1000/sja1000.c
