SPI

[Bala]

Hi,
What is the SPI Clk operating Frequency for A64 Board's SPI in UEXT1 connector (SPI0)? I tried to check user manual as well as A64 SOC Data sheet, I couldn't find it.

Hi
I mean, max freq for SPI_CLK supported by A64, I tried to check that in A64 data sheet, there is no info on max clock speed of SPI_CLK. Can you please help?

In the Olimage images it is 10Mhz. Source:

spi-max-frequency = <10000000>;

Thank you

Other question, can a64 be used as slave SPI device? And if so, how.

I guess that's can any Linux SPI be a slave... (don't know, but might be found on the net or asked on Linux places).

Is there HW and SW forum JohnS about A64 or you can send me (same way you did...) to better paces where we can talk about how to implement SPI slave driver on A64 chip runnin olinuxino image...... GJ Hero Member JohnS
