Hello, I am writing this mail to get some advices for my problem I am suffering from.
I am currently testing my MCP2515 CAN module to test CAN communication via Beaglebone black.
However, when I connected MCP 2515 via SPI and powered ON, the UART consol just prints ‘CCCCCCC..” repeatly.
I know that this message prints when the BBB couldn’t find proper bootable image. However, the booting is done successfully when I disconnect the MCP2515.
That is, it seems that the SPI devices are conflicting with EMMC or uSD.
I tested booting with these combinations:
EMMC booting – SPI0 (boot fail)
EMMC booting – SPI1 (boot fail).
uSD booting – SPI0 (boot fail)
uSD booting – Spi1 (boot fail)
Please give me some advices to solve my problems..
Best regards.
