In i.MX 6Dual/6Quad Applications Processor Reference Manual I have found:
"i.MX 6Dual/6Quad supports Little Endian mode only."
as well as:
"The Cortex-A9 Core Platform supports little endian mode only. Big Endian is not
supported even though both modes are supported by the Cortex-A9 processor."
What does it mean in practice? Does it mean that i can't manually change endianness by "SETEND" command?
But when I try this code:
*(unsigned long *) 0x20000100 = 0;
*(unsigned long *) 0x20000200 = 0;
__asm volatile ("SETEND LE \n\t");
(*(unsigned long *) 0x20000100)++;
__asm volatile ("SETEND BE \n\t");
(*(unsigned long *) 0x20000200)++;
it seems that everything is ok (I mean value at 0x20000100 is in Little Endian mode and value at 0x20000200 is in Big Endian mode):
