Linux driver for i.mx6 flexcan mailbox

[shabeerbadarudh]

Hello,

I need to configure the flexcan in imx6 for mail box reception and transmission(I want to use complete 64 mailboxes). But the current driver support only FIFO reception(Linux kernel 3.0.35). From where can i get the driver for mailbox?  or can we need to write the code from scratch?. Please give some replay or send me the useful links/codes  because i need to complete  this task with in a short period...

Regards

Shabeer

Hi Sorry for the late replay...

We implemented the mailbox reception logic in flexcan driver.

Hello,

I know this post is old, but I wander how do you code the mailbox reception. I am trying to do the same thing using socketcan but i don't know if i have to use a completly different system (like sysfs) to access the Mailbox buffer or if it's better to modify directly the socketcan lib to access it.

Thanx for your reply.

Sorry for the late reply. We had implemented it in the flexcan driver, not done anything on to the upper layers

Thanks,

Hi,

After checking the code, you are right , the driver only supports Rx FIFO.

You would need to implement your own driver to add the single MB reception.
