Hi,
im using iMX6Q device and set next boot mode - BOOT_MODE[1:0] = 0b01.
I connect USB cable to PC and to OTG1, but no activity on PC (checked by USB View utility).
Im able to connect with JTAG to Cortex-A9 core and step in BootROM.
Please give me right direction, where i should check.
Hi Artsiom
if you have jtag one can run USB Device SDK test
(imitate iROM in some manner)
Also please check Chapter 8 Avoiding Board Bring-up Problems
Chapter 2 Design Checklist
IMX6DQ6SDLHDG IMX6DQ6SDLHDG, Hardware Development Guide
Also it may be recommended to test with other computers, preferably with Windows XP.
Best regards
chip

Hello, thank you for advice.
I checked with JTAG - PLLs are not started!
How BootROM should configure it? (Maybe exist dependence from Config pins?)
Yes, i can start code in RAM (0x0090 0000). My little software relase Ethernet PHY from reset by GPIO.
ARM core is working, but only at 24MHz
I think you can check with oscilloscope
signals on NVCC_PLL_OUT,
VDD_ARM_CAP LDO and other LDOs.
Best regards
