imx6ul BOOT mode problem

[lance_lau]

imx6ul BOOT mode problem, IMX6UL I designed, the storage selection is EMMC, BOOT is set to LCD_DATA11, LCD_DATA6, LCD_DATA5, LCD_DATA1 is high level, after power on, no matter BOOT_MODE1, BOOT_MODE0 is (1,0) or (0 , 1), the boards are all HID-compliant devices, and the USB devices are not recognized after an abnormal interruption in the programming process.
Using the NXP official DDR test tool, read out SRC_SBMR1 (0X020d8004) = 0x00000862, SRC_SBMR2 (0X020d801c) = 0x02000041, but the default SRC_SBMR2 (0X020d801c) = 0x02000001 in the specification, compared with the IMX6UL development board that can be burned, its SRCXdB801 ) = 0x02000001 or SRC_SBMR2(0X020d801c) = 0x01000001.

At present, the level status measurement of the BOOT configuration item meets the programming requirements. The DDR stress test can pass, but the programming still cannot be performed normally. Please help, thank you.

Hi 辉 刘 

may be suggested to check with oscilloscope boot configuration

and after boot fail, attach jtag and check registers SRC_SBMR1,2 -

they should correspond to choosen boot configuration, description

can be found in sect.8.3.2 GPIO boot overrides

i.MX 6UltraLite Applications Processor Reference Manual

Just for test try to extend POR up to 1 sec.

Best regards
igor

The read SRC_SBMR1(0x020d8004) = 0x00000862, corresponding to the selection of EMMC mode, the BOOT configuration item was also read with an oscilloscope at power up, which is consistent with the software read, but it is always a HID-compliant device, use Mfgtool to download The program will fail.

[igorpadykov]

suggest to check emmc boot flow with oscilloscope and test its signals,

then check with logic analyzer where exactly boot fails: which emmc command fails.

Best regards

HI igor:

   Thank you for your answer, we shouldn't enter the program startup yet, it just went wrong during the boot process,

the relevant log is as follows:
