Dear All


There is the custom board using IMX6SX & PF3000 instead of PF0200.


It can't detect SDCard 4 when booting as follows.

___________________________________________________________________________________________ CPU: Freescale i.MX6SX rev1.4 at 792MHz CPU: Automotive temperature grade (-40C to 125C) at 32C Reset cause: POR Model: Freescale i.MX6 SoloX SDB RevB Board Board: MX6SX SABRE SDB DRAM: 1 GiB PMIC: PFUZE100! DEV_ID=0x30 REV_ID=0x11 MMC: FSL_SDHC: 0, FSL_SDHC: 1, FSL_SDHC: 2 MMC: no card present mmc_init: -123, time 9 *** Warning - MMC init failed, using default environment Display: Hannstar-XGA (1024x768) ___________________________________________________________________________________________


I found out there is no 3V1 suppiled to to SDCard4 VDD.


I didn't apply any patch for PF3000 and I think I have to apply PF3000 patch to u-boot.


I'm using imx-yocto-L4.9.88_2.0.0 now.


Please let  me know how to do it.
