CONFIG_SPI_MPC83xx: Freescale MPC83xx SPI controller

The documentation is even worse. So we will find out ourselves, for good or worse. Protecting the IoT with Invisible Keys.

Can you try spidev: General response, not knowing the MPC: This book contains many real life examples derived from the author’s experience as a Linux system and network administrator, trainer and consultant. As a longtime user of Motorola processors and documentation I have always been very impressed with the quality and consistency of the user manuals 68xxx and 8xxbut the latest round of 83xx and 85xx has been disapointing at best.

How to implement this? On top of that their web-based “support” sucks. Find More Posts by NishaK. I let Freescale know what I thought. Or you might get lucky and find a device mpc83xc includes the above functionality in a convenient form If we would decide to go this way, suddenly a wonderful world of new possibilities would open, but for obvious reasons we will try to stick to the existing approach.

Linux Kernel Driver DataBase: CONFIG_SPI_MPC83xx: Freescale MPC83xx SPI controller

Introduction to Microcontrollers Mike Silva. The device tree allows you to find zpi where your device is connected and how it is configured. I expect even with the lower bit rates a very high CPU utilization, which could not be accepted, since other tasks have to be executed as well. Last edited by NishaK; at In kernel im not getting the code flow and how gpio interacts with with the spi driver code.

There is a way to add it in device tree file. Here you can get whether the Chip Select signal is active high or mpc83cx low. SPI interface in mpc83xx Hi everyone, I have to write an application in linux Moran h Old Field Ct.

The documentation was clearly written by someone who does not understand the english language, and appears to not have been proof-read. Processor im using is mpc and chip select signal to SPI has given using processor gpio.

I have not done a measurement. Ive already read that document. Is there any other way add? Electrical Engineer – Power Electronics Lead the design of kW-level power systems for mpx83xx satellites, manage and Chronological Newest First Hi, In our project, due to some restrictions and requirements we would have to use the SPI of a Frescale MPC83xx for receiving a continous stream of serial data at a bit rate of at least kbps, but would like to use modes with up to 12 Mbps as well.
