It's MPC8323E-RDB. Using spidev_test utility: [EMAIL PROTECTED]:~# ./a.out -D /dev/spidev1.0 spi mode: 0 bits per word: 8 max speed: Hz (kHz): 500000 (500) ... [EMAIL PROTECTED]:~# Then trying change bits per word to 32: [EMAIL PROTECTED]:~# ./a.out -D /dev/spidev1.0 -b 32 spi mode: 0 bits per word: 32 max speed: Hz (kHz): 500000 (500) <---- hang Board is still alive, but SPI isn't. Though, there are various steps to reproduce the same. So SPI unit should be really turned off to change mode.
