Can't flash klipper on canbus

[jwhite]

I'm getting this error when I flash klipper with a 16k offset using the canbus.

The board has a fast flashing led (very fast) and doesn't seem to work after the flash.

Flashing klipper without canboot work fine.

Well Octopus boards (F407, F429, F446) are 32K offset and the H723 is 128K offset.

EBB’s are 8K offset.

SB2040 I flashed previously with 16k offset worked. This one doesn't. No idea why.

[NAPCAL]

SB2040 is not a BTT product; the BTT EBB SB2209 & SB2240 are BTT products.

The boot offsets I listed are for BTT products; I don't have or provide guides on other manufacturers' products.

[treaves]

@NAPCAL yes, BTT does make a CAN EBB that uses the SB2040 in addition to the other two.

[NAPCAL]

@treaves You are mixing up drivers with processors.

The SB EBB are 2209 or 2240 The SB2209 can come with a STM32G0Bx or RP2040 there is no SB2040 Processor.

There is a https://github.com/Mellow-3D/Fly-SB2040 that is not a BTT product.

I see. Thanks.

I'm getting this same error on an EBB2209 RP2040.
