Hello, I am using Hummingboard IIOT and generated image using bitbake as given in [https://github.com/SolidRun/meta-solidrun-arm-hailo](https://github.com/SolidRun/meta-solidrun-arm-hailo). Then i uploaded uart flashing firmware and system and reflashed QSPI content. But when i loaded u-boot-tfa.itb in the SOM it shows the following error evenif the uboot menu can be accessed. So it is prohibiting to flash eMMC content.

## Loading kernel from FIT Image at 85000000 …
