Hi Hanson

in general (unfortunately nxp does not provide such examples) it is possible, for example

setting application ivt addresses to On-Chip RAM - OCRAM, described in

Figure 6-18. Image Vector Table i.MX 8M Dual/8M QuadLite/8M Quad Applications Processors Reference Manual

AN12107 in sect.2.5.1 IVT data structure gives more detailed description of ivt usage

i saw the DDR tools has a firmware ,and that firmware did not use the uboot to bootup imx8mq.

how can i compile that firmware?

[igorpadykov]

sources of that firmware are not available for customers.

In general it uses the same concept as suggested above.

So Did any compiler or ide is provided by nxp can doing this?

[igorpadykov]

this does not depend on compiler or ide, it is necessary to write custom

application for that.
