I'm find an uncahed area to be used as the BD of ENET for Cortex-M4 of i.MX6 SoloX.
And the TCM_U(Upper Tightly Coupled Memory) may be satisfied.
But When I use it as BD of ENET(setting addresses value with TCM_U area to ENETx_RDSR/ENETx_TDSR registers, the ENET doesn't work.
If I use the DDR address space as BD, the ENET works fine.
Except for the BD settings, all other settings and configuration process are same for these 2 situation.
I'd like to know is the TCM_U capable of being used as BD area of ENET?
If yes, is there any configuration to be done for it?
