At i.MX8MQ, we can use UUU SDP to download data (~2K bytes) to a memory address.

e.g.  
uuu sdp: write -f data.bin -addr 0x184000

However, i.MX8M Plus changed to SDPS. How to use SDPS to download data to a memory address 0x184000.

The main purpose is to load the DDRC setting without rebuilding the uboot.bin file. Just download the data to memory and use it at bootup.

I would recommend you reference the mfgtools documentation. This is an NXP tool and not something specific to SolidRun hardware. [Sample script · NXPmicro/mfgtools Wiki · GitHub](https://github.com/NXPmicro/mfgtools/wiki/Sample-script)

You should be able to use spdv: to accomplish the same thing.
