Hi Kevin,
I check the log [0], it seems first time mt8135-evbp1 boot to kernel shell successfully, then boot again. In the second time, mt8135 stay in fastboot mode, waiting host send boot image, then timeout.
I download zImage and dtb in [1], and kernel run to shell successfully on my platform.
I don't know whether this issue caused by test environment or not.
