We are currently developing a firmware for Antminer S19. The plan is to have a first release available during the first half of December 2021. Once available, we will update this page.
S19j: Identify control board type - Xilinx or BeagleBone
The firmware for Antminer S19j and S19j Pro is different depending on the control board type. Antminer S19j and S19j Pro can either have a Xilinx or a BeagleBone (BB) control board. It's important to identify the control board type in order to download the correct firmware type. Antminer S19 (without J) is always using Xilinx.
The Xilinx control board has the SD-card reader is located next to the Ethernet port, exposed to the outside of the Antminer.
The BeagleBone control board has the SD-card reader located on the inside and requires the Antminer to be opened before it can be accessed.

Frequently asked questions
Which versions of Antminer S19 will be supported?
The firmware will support S19, S19 Pro, S19j, S19j Pro and T19.
How is the firmware installed to the Antminer?
In contrast to our other Antminer firmware, the Antminer S19 firmware will not be installed (flashed) on the Antminer, as Bitmain prevents any custom firmware from being installed. It isn't possible to install (flash) via a micro SD card either. Instead, our Antminer firmware runs directly from the micro SD card. When the Antminer is starting, it will load our firmware from the micro SD-card.
Do I need a large number of Micro SD cards?
Yes, one per Antminer you have. As the Antminer will boot and load the firmware from the SD card, the card must be inserted in the Antminer all the time while running. For this reason each Antminer will use one SD card. If you have 50 Antminers where you want to run the Awesome Miner Antminer S19 firmware, you need a total of 50 Micro SD cards.
How do I uninstall the firmware?
As the firmware is never installed on the Antminer, you simply remove the SD card. When you start the Antminer without the SD card it will simply load the default Bitmain firmware that is already installed on the Antminer.
What kind of Micro SD can be used?
Antminers can be sensitive about the Micro SD card being used, where cards with larger memory (16 GB or above) may not work in all cases. Bitmain typically recommends 8 GB Micro SD cards or smaller. If you run a larger number of Antminers, please make sure you verify the specific type of SD card is working before ordering any larger quantities.
