MPC83XX SPI DRIVER DOWNLOAD
BTW, we are running Linux 2. And GPIO in processor has control of chip-select to the slave device. Ive already read that document. This book contains many real life examples derived from the author’s experience as a Linux system and network administrator, trainer and consultant. I let Freescale know what I thought. Our system has a 32MHz oscillator.

Did I miss something and there are efficient ways of using the SPI also with continously high data rates?

Sorry for the “schrieb” – Googles interface tricked when I was looking in the other direction Note that registered members see fewer ads, and ContentLink is completely disabled once you log in. Ive already read that document.
CONFIG_SPI_MPC83xx: Freescale MPC83xx SPI controller
View LQ Wiki Contributions. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own. BTW, we are running Linux 2.
Once again my processor is powerpc with 83xx platform Thanks in advance -Nisha K.
Is there any other way add? Could you please kpc83xx your experience and provide some numbers bit rate versus CPU load? And GPIO in processor has control of chip-select to the slave device.
The documentation was clearly written by someone who does not understand the english language, and appears to not have been proof-read. Visit the following links: Linux – Kernel This forum is for all discussion relating to the Linux kernel.

SPI api in mpc83xx Hi everyone, I have to write an application in linux 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. The time now is Protecting the IoT with Invisible Keys. Since our SPI traffic is short and bursty rather than continuous, the performance impact is likely in the noise.

I expect even with the lower bit rates a very high Sp utilization, which mpcc83xx not be accepted, since other tasks have to be executed as well. I let Freescale know what I thought. In kernel im not getting the code flow and how gpio interacts with with the spi driver code.
For more advanced spj it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. Hi everyone, I have to write an application in linux I have added the following lines in spi controller node and defined child nodes.
