NIOS II e -> No data cache, No instruction cache. So, No cache bypass required.
NIOS II f -> Like normal processor, it has caches. But, MMU is optional. If MMU, 32 bit address width and Cacheability is configured via TLB. If, no MMU, 31 bit address width and 31st bit is used for cache bypass (non-caching address).

For Gen2, the alignment of non-cacheable memory should be multiple of 32 as the Cache snooping does not exist here.

Use, HAL functions!

It has optional MMU and I think iOS does not consider MMU presence in both NIOS II classic and GEN2

Look at the \\sempc1\boards folder


=> mmc dev 1
switch to partitions #0, OK
mmc1 is current device
=> mmc rescan
=> fatls mmc1
** No device specified **
=> fatls mmc 1
** Unrecognized filesystem type **
=> fatls mmc 1
