Hi,
we are using IMX6 SOM with Debian Linux version 3.10.101-imx6,
where SPI device (ATMEL AT86RF233) is connected to.
We have encountered a problem while reading from the device more than 64 bytes via SPI.
Reading data of less or equals 64 bytes works fine.
The SPI reading process is as follows:
- prepare spi_message and spi_transfer structures and fill them with relevant data: spi_device , data tx, transfer len , complete handler , …
3. The read itself is done by calling spi_async function
4. The completion handler function is called and prints the read message, but trying to read more than 64 bytes in one SPI transaction causes the read data to be corrupted.
Do you have any idea for this behavior ?
Is there any limitations for
Is there (in Linux) any definition for the max size to be read via the SPI ?
Thanks
