hi folks,
i am not very familar with driver model until now and so i've a question.
I'm trying to bring up my Zynq ZC702 evalboard using driver-model during SPL stage (because QSPI needs this). I simply switched on "Driver Model for SPL" within Kconfig and compiled.
This ends up in:
U-Boot SPL 2015.10-rc4-00050-g996ec1d-dirty (Oct 07 2015 - 13:57:32)
spl:board_init_r()
using memory 0xffff10c0-0xffff20c0 for malloc() spl_init() dm_init() failed: -2 dm_init_and_scan() returned error -2 ### ERROR ### Please RESET the board ###
i had a look into drivers/core/root.c and saw that
device_bind_by_name(NULL, false, &root_info, &DM_ROOT_NON_CONST);
fails.
Any idea why the root-driver cannot be found ? Maybe there are some switched need to be switched on too.
thanks, Hannes
