Hi,

 

We are running with the following, but u-boot is not possible
Booting with micro SD card in SD1 slot
CPU:MCIMX6L3DVN10AC
DDR3L:MT41K256M16TW-107:P
The following shows the waveforms of POR_B, SD_CLK, and POR_BPOR_B, SD_CLK and POR_B waveforms
Since U-BOOT is not possible, there is no UART output and DDR stress test is not possible.
Please tell me the reason why U-BOOT cannot be started and the countermeasures.
