SDP vs SDPS: whats the difference ..?

[dry]

Cannot see any reference in iMX8 UG to SDPS, SDP still there.

What is the actual difference ..?

UUU help traces/messages are kind of cryptic on this:

What is "stream download.." here ..?  Is "boot" the only command supported here ..? 

Where does SDPS come from?

[joanxie]

refer to the uuu document

Support SDP protocol (i.MX6x, i.MX7, i.MX8M, i.MX8MM)
Support SDPS protocol (i.MX8QXP B0, i.MX8QM B0)

Thank you for replying, but:

Support SDP protocol (i.MX6x, i.MX7, i.MX8M, i.MX8MM)
Support SDPS protocol (i.MX8QXP B0, i.MX8QM B0)

What does this say about how the protocols differ .. ?  Is the difference only that the Same protocol is called SDPS on iMX8 ?

Why I do not see any SDPS reference in the User Guide for iMX8 ? There is still SDP I see.

Is SDPS a UUU variant of SDP ..?

[joanxie · Accepted solution]

in the uuu script, you can find

# This command will be run when i.MX6/7 i.MX8MM, i.MX8MQ
SDP: boot -f _flash.bin

# This command will be run when ROM support stream mode
# i.MX8QXP, i.MX8QM
SDPS: boot -f _flash.bin

Thank you,

seems like they identical, perhaps some fix in uuu was done for difference in SDS between the ROM code of the respective SOCs ...  Speculating.
