i have a board based on i.mx6 quad processor. The board was not booting from micro SD(SD4 interface) and standard SD(SD1 interface). While checking SD clock i found initial identification 347.22khz itself not obtained. Can you able to tell the reasons for not obtaining initial identification clock ?
HI vineeth
this may be caused by some errata like ERR006282,ERR007926 IMX6DQCEC or
by hardware : please check IMX6DQ6SDLHDG Chapter 8 Avoiding Board Bring-up Problems
and test SD interface with i.MX 6Series Platform SDK : Bare-metal SDK
Best regards
igor
