Hi,
I have designed an i.MX6Q test board refer to the schematic provided on the NXP official website.In the i.MX6Q test board,the VGEN4 of MMPF0100F0AEP output voltage was 3.24V,was this output voltage is normal?If I need the output voltage of VGEN4 is 1.8V,how can I make it realized?
Thanks for your attention!
Hi,
我重新焊接了一块板,跟之前的板是同一批板,只焊接MMPF0100F0AEP这一部分电路,不焊IMX6芯片及其它部分的元件,这样测到MMPF0100F0AEP跟部分输出的电压都正常,VGEN4输出的电压是1.8V,再将从原先VGEN4输出3.24V的板上拆下MMPF0100F0AEP换到新焊接的只有电源部分电路的板上时,VGEN4输出的电压也是1.8V。这说明MMPF0100F0AEP芯片和电源部分电路应该是没有问题的,可能是电源以外的电路影响到VGEN4的电压输出。
这个问题现在还未能解决。
我的是烧录系统时卡在Loading U-boot这一步
