Any way to enter i.MX8qm via MfgTool2 to serial download mode in software?

[yibhan]

Hi guys,

I am using imx8qm mek with emmc in linux 4.14.98 and I'd like to know how to enter to serial download mode in software without changing dip switch.

Unfortunetly, I can't use "bmode usb" in uboot, bsp of imx8qm mek doesn't support bmode command anymore.

Do you have any comments to solve my issue?

Thank you

you need use bmode in uboot, right? I checked the uboot source code, refer to the makefile:
ifneq ($(CONFIG_SPL_BUILD),y)
obj-$(CONFIG_CMD_BMODE) += cmd_bmode.o
obj-$(CONFIG_CMD_HDMIDETECT) += cmd_hdmidet.o
obj-$(CONFIG_CMD_DEKBLOB) += cmd_dek.o
obj-$(CONFIG_IMX_VSERVICE) += imx_vservice.o
endif
if not load spl , bmode should be supported
