Hello
I made a new board with reference to EVK(8MMINILPD4+BB).
AP, DDr, eMMC, etc. are all configured like EVK.
However, the USB OTG part for image download uses micro USB instead of type-C.
Therefore, all circuits such as Type-C side ICs were removed.
I get an error when I make a board and download an image through UUU
So I searched and it seems that UUU is only possible with type-C
If so, can't I download the image?
Isn't mfgtool even possible?
Please let me know how
UUU works when the processor is in serial download mode. If you put bootable image on eMMC or SDcard, UUU would not work because the processor is not in the serial download mode when it boots normally.
UUU should work on micro-USB connector as well as Type-C. Make sure USB works in normal case, such as keyboard or USB thumbdrive. Also get command line tool from Release 1.3.82 · NXPmicro/mfgtools · GitHub for testing.
Hello,
For UUU to work you'll need to disable all dependencies of the Type-C connector for uboot to start correctly.
In your defconfig:
CONFIG_USB_TCPC = n
In your dts file:
&usbotg1
{
--- drm_mode= "otg";
--- extcon = <0>, <&typec1_ptn5110>;
--- picophy,pre-emp-curr-control = <3>;
--- picophy,dc-vol-level-adjust = <7>;
status = "okay";
};
&usbotg2
{
--- drm_mode= "otg";
--- extcon = <0>, <&typec2_ptn5110>;
--- picophy,pre-emp-curr-control = <3>;
--- picophy,dc-vol-level-adjust = <7>;
status = "okay";
};
Hope this helps,
Best regards,
Aldo.
