Issues about U-Boot Transplanting on MX6DL

[tony_l_cai]

Dear all,

     we are transplanting U-Boot 2014.04 on MX6DL, and refer to i.MX 6Dual/6Quad BSP Porting Guide.pdf, we have ported the u-boot. At the beginning, our uboot flash into emmc, it doesnt work, because we flash the uboot.bin to emmc not uboot.imx, and now it can go. but the uboot will hang after going for a while. the log will stall as blow:

U-Boot 2014.04 (Jul 15 2015 - 11:03:02)

CPU:   Freescale i.MX6DL rev1.1 at 792 MHz

CPU:   Temperature 44 C, calibration data: 0x5b25245f

Reset cause: POR

Board: MX6-SabreSD

I2C:   ready

     Then we append some log to find the pinpoint. and it will hang as blow:

So whats wrong in u-boot porting, maybe? Please give me a hand, 3Q~

Hi tony

this may be caused by heating or poor power supplies (for example ripples).

So heating up the part causes more failures, then the drive strength is too

low and the signals may not rise/fall fast enough. You can try to cool parts with spray

and check. Other option slow down frequencies processor and memory.

One can try uboot mtest

linux - How can I test the RAM for data corruption on an ARM-based system? - Unix & Linux Stack Exch...

Best regards
