That was the problem. Looking for complete solution is OT on SO. Always read the FIFO “input” register.
spi: driver for Cirrus EP93xx SPI controller
Sign up or log in Sign up using Google. Can we have some more detail ep93xxx what you’ve tried, exactly? So if you have some generic standard SPI driver, it will probably not work. Ok guys Thanks all for the suggestions and tips. Post as a guest Name.
That was the problem Solution: Their support seems eep93xx for this question: The ARMT’s bit microcontroller architecture, with a five-stage pipeline, delivers impressive performance at very low power. It does not matter if the slave device reply or not!
Any code or example? A two-port USB 2. What do you mean with our attempts have failed. First of all thanks for the reply.
[PATCH 0/3] spi: driver for Cirrus EP93xx SPI controller
High-Performance, Networked, ARM9, System-on-Chip Processor
Due to the fact i was not using drivers but i was bitbanging bits directly in the micro register I had a collateral effect: If I remember correctly, the LIS accelerometers don’t follow the SPI de facto standard very well, but have various obscure timing specs. By enabling or disabling the EP’s ep93xd interfaces, designers can also reduce development costs and accelerate time to market by creating a single platform that ep933xx be modified to deliver differentiated end-products.
Solutions Voice Playback Record Control. Block Diagram View Full Image. The ARMT core operates from a 1. This coprocessor greatly accelerates the ARMT’s single- and double-precision integer and floating-point spo capabilities, enabling the EP to perform high-speed mathematical calculations when encoding digital audio and video formats, processing industrial-control algorithms wp93xx performing other math-intensive computing and data-processing functions.
Software and Tools Software and Design Resources available by request. Email Required, but never shown. Our approach to the problem is literally based on bitbanging the EP registers like in this example provided by the Embedded Arm file tempSensor.

I resolved my problem.
