Hello,
I recently bought a 1Gb, no eMMC Zero 3W, but am disappointed to find that it seems to be defective.
It gets stuck at the Rockchip TPL(DRAM init) on every boot UNLESS I press down on the RAM chip. Seems like Radxa did a really horrible job with their soldering and X-Ray inspection for the BGA Packages.
The chip and PMIC also gets uncomfortably hot in this state.
I’ve tried multiple PSUs, multiple SD cards and multiple OSes, including custom U-Boot builds. Only thing that helps is pressure on the ram chip.
I have requested their authorized vendor, who I bought the device from, to offer me a replacement but even after sending them a detailed video they just told me to contact Radxa.
Has anyone faced such an issue?
