Unable to use emmc drive

Hi, folks.
I am now unable to boot from emmc drive. Did clean it with blkdiscard /dev/mmcblk1. I am unable to flash all firmware images with upgrade_tool (using debian 18.04 host) through usb-c cable. The error messages are "Test Device Fail" and "Creating Comm Object failed!" when using "upgrade_tool uf Firefly-RK3399_LinuxSDK_xubuntu16.04_20181011.img". I only able to boot from the Firefly-rk3399_xubuntu1604_SD_201705151725.img. This is getting frustrating. The documentation will not help in this case.

Is it somehow possible to flash the emmc drive with or without upgrade_tool?

Seems you have found the solution: start with sd boot and wipe eMMC

@penguin That is exactly what i did. Got the firefly SD image from 2017 and did use etcher to put in on SD. Then I could boot firefly rk3399 and wipe out emmc drive and make new ext4 file system. Thanks for your advice.
