Flashloader: Steps to getting CAN enabled?

p_shep — Mon, 25 Jan 2021 16:49:16 GMT

Hello,

Our setup would be programming a user application to an RT1064 over CAN-FD. Initially I was figuring that we'd have to entirely write our own, but then I saw that NXP already had the code for a bootloader, and that it supported CAN. Wonderful!

But after reading about CAN being an option for programming an application with Flashloader... it would seem it's not. (use to be?)

Anyway, in order to get it working, it looks like I'd need to to do the following steps:

- Add a new interface to g_peripherals for CAN-FD

- Add a PCAN driver to ~~sdphost~~ blhost?

Would that cover it? Would that allow the continued use of the other tools (mfgtools etc)?

Looks like a package blfwk is missing from the sdphost code...

But the blhost code is available from here:

So buspal, which blhost connects to over serial, is supposed to run on another MCU? And that's supposed to do the translations from serial to i2c/SPI/CAN?

Could I add the P-CAN interface directly to blhost?

Hello @p_shep,

That's right, this software is used to translate the commands send by the blhost to the CAN format. If you want to directly communicate another device with the flashloader, you would need to follow to check the command structure in the following link.
