According to the hal api reference (http://www.altera.com/literature/hb/nios2/n2sw_nii52010.pdf), the alt_flash_write and alt_flash_read functions are NOT thread safe.

I beleive the above mentioned functions just use function pointers to alt_epcs_flash_write and alt_epcs_flash_read when using EPCS so I would assume that the alt_epcs_ functions are also not thread safe. I am not sure if Altera really intends for you to use the alt_epcs_ functions directly.
