CANFD on ST32H7

2020-12-17 Thread Frank-Christian Kruegel
Hi, I'm currently in the process of testing all peripherials on my Nucleo STM32H743ZI board. So far, I2C, SPI, UART, and Ethernet seem to work. My next step would be CANFD, but I've noticed that there is no stm32_can.c/.h in arch/arm/src/stm32h7 as there is for stm32f7. Since the F7 doen't

Hi Frank-Christian, I don't know whether it's on anyone's to-do list, (I just joined this mailing list a few weeks ago myself), but I "CAN" say that if you are interested in writing your own driver it shouldn't be terribly difficult (I'm working on a driver for the TI Tiva chips currently). As you

Dear Nuttx, I'm trying according to your instructions. But still cannot read sensor. I don't understand why ID is 0x. [cid:07735f7d-1a47-42b7-b827-0e7af231fa04] Is it related with SPI CS pin. I tried with MEMS Chip select pin to 1. ground 2. PC1 [cid:9cafed8e-3666-4626-8067-7

To debug this type of problem you need to be able to observe the activity on the SPI bus. A 4-channel scope would be ideal, but you can do it with a 2-channel scope. Most likely, you are not routing your "SPI chip select" to the appropriate GPIO pin. That could be caused by several factors.
