So i bought prebooked rock 5b when it got released, so got a coupon, and one of the few people to order it when it was released,
after i got the board, i tried multiple power supplies, wasted so much money for power supplies, and even bought the official radxa power supply and tried booting it,
and that too failed.
after reaching out to the allnetchina for this issues, they wanted me to ship the board back to china, which was quite impossible, and there is no way i can send it from my country.
i had travelled to china for some work visit, and i took the board with me to china and then shipped it locally to allnetchina office, and they took good amount of time and found that there was a faulty ic and they assured me that it is fixed and shipped me the board, after i received the board, i tried booting most of the images that were available and none of them booted, only radxa image that was then available booted. none of the other images boot on my rock 5b.
i tried reaching the allnetchina team for their support and they arent responding.
these boards are capable, but when the manufacturer makes a mistake by sending untested dead board to customers, why should i a customer face all the trouble to get it fixed, and when i took the long way to send it back for rma, they screw me again, they sent back a faulty board, they didnt even replace the whole board and give me a working one instead.i am totally vexed with this board.
this is the serial out that i am getting when trying to boot armbian, if any one can help please do.
