Hello everyone,
There are many blank areas which are undocumented, this LCDIF
CRC32
feature, i.MX8M Mini Arteris NOC at 0x32700000 , the ARM GPV NIC-
301
at
0x32{0,1,2,3,4,5,6,8}00000 and their master/slave port mapping.
The
NOC
and NICs were documented at least up to i.MX6QP and then that
information disappeared from NXP datasheets. I think
reconfiguring
the
NOC/NIC QoS would help mitigate this shift issue described below
(*).
I also think the QoS would help if it is configureable.
It is programmable, it's just the port mapping which is undocumented.
Do you know if there is some additional NOC/NIC documentation for
i.MX8M
Mini available ?
No.
Can you ask someone internally in NXP maybe ?
Maybe, you may try community.nxp.com, like the i.MXRT case.
The community.nxp.com is unhelpful, the i.MXRT case it a good example --
the solution to the problem has been found by the person who asked the
question on their own, and elsewhere too.
But note that the i.MXRT interconnect documentation is available in the
i.MXRT datasheet, which made that possible in the first place. On i.MX,
all that information has been removed from the datasheet in i.MX7 and
i.MX8M, so I cannot even help myself, even if I wanted to. This is very bad.
