Hi Igor,
Do you mean we need authentication for the "SP" version before download? Is there anyway to download the image without authentication?
If not, which tool can be used for the authentication? IMX_CST_TOOL or other?

Hi john_li2
" SP' - Security Production, the same as HYBE_TYPE_PDODUCT:
fuse SEC_CONFIG[1:0] - 1x—Closed (The program image executes
only if authenticated)
"SE" Security Engineering
SEC_CONFIG[1:0] - 01—Open (allows any program image,
even if the authentication fails)
described in Table 8-2. Boot eFUSE descriptions
