First of all, I'm a hardware engineer.
I am currently using IMXRT1062CVJ5A(New Board).
I uploaded a U-boot image to IS25WP128(NOR Flash) using FlexSPI(QSPI),
But IS2s16160(SDRAM) does not work and Flash does not work...
(Waveform measurement with : oscilloscope : Clock, CE, etc....)
By the way, the system clock of MCU(Imxrt1062) is normal operating at 24MHz...(used oscilloscop)...
Flash IC seems to be a problem, I remove the Falsh chip with the U-boot and soldered it to 1060EVB.
=> Normal operaion !!
In a New borad(IMXRT1062CVJ5A), voltage level and clock are all normal.
What more should I debug?
(The difference from the 1060 EVB reference circuit is that the part of the free link is removed.)
