Vladimir,
I seem to recall a colleague of mine mentioning something about a similar
issue. I can check with him and get back to you, unless you already have
a solution...
Cheers,

Hello to anyone!!!
I've made some NIOS design with SPI and wrote small source code
....
while(1) {
usleep(10);
alt_avalon_spi_command(SD_BASE, 0,
6, write_data,
1, read_data,
flags);
}
....
but when I saw SCLK on Proto2 by oscilloscope, the SCLK's pin was "0" always,
SS_n was changing, MOSI was "0" and MISO was changing too (it's very strange).
I checked pin assignment and there is OK.
Maybe someone knowns what kind of problem I had there?
Thx.
