Same as PS3's NVS, used for storing tokens and flags. You can access it by using the function icc_nvs_read (or by ftp'ing the respective regions with root flags server).<br> | |||
Seems that a total of 7 regions(blocks) exist in 2 banks, main bank and backup bank <br> | |||
The kernel accesses only the 5th and the 2nd region, however it's possible to read the other 5 (also the entirety of it by reading /dev/sflash0s0x34 with BUF_SIZE 0x200 from ftp ).<br> | |||
Most, if not all, of the NVS regions can be accessed also in sflash, starting with offset 0x1C4000. | |||
