Topic: I have a problem with my antminer s19 (Read 160 times)

Thank you all so much for the recommendations…i have fixed the problem and it works mow thank you so so much

You will need an OTG flash drive to be able to flash this unit or you need USB to OTG adapter cable to flash the unit.
There is a detailed guide on how to flash the unit check the link below.

- https://www.zeusbtc.com/articles/asic-miner-troubleshooting/3900-antminer-s19-card-flashing-a113d-control-board-firmware-tutorial

About the Xilinx board, it might be an incompatibility issue which is why it does not work or it using different firmware.

Oh okay i didnt know um new here….and the control blard is amlogic with a micro usb plug instead of a memory card reader how do i flash it? And i didnt try each board individually i will try it tomorrow and i do have another control board but its an xinxlin control board and it didnt work on the miner i dont know why…it doesnt report ip at all

Looks like a software issue no? or a faulty control board ?

Have you tried to flash the firmware? do you have another CB to try with?
Have you tried with only 1 board connected at a time?

You should use the code formatting, like this:

Hey guys…..please help me…i have a new antminer s19 90th model with amlogic control board and APW121417 version b power supply unit…for some reason everything but the realtime hashrate is normal but the rest (fan speed normal pool normal my pool also shows the worker but with 0 hashrate)…the hashboards are cold i will attach the miner log down in the text….but also on the control board the red (fault light) is long on (it should be off) and the green (normal) light is off instead of flashing…..i am from africa so no way to return it back but i can get spare parts like psu or control board…anyone can help me please help me !! Thank you so much
