## Context - I received the board in December 2022 🙂 - was too busy, but I was an early adopter for crowdfunding Now it is time to use it ! - Turing Pi 2 (December 2022 !!!!) - Maybe in version 1 of the firmware (early board) - Turing RK1 x 4 - RAM: 16 GB What I Tried I followed the official documentation to flash the firmware. I placed the firmware file on the SD card as instructed. Actual Behavior The firmware on the SD card is not being recognized or used during boot (no led from lan port) The device does not enter firmware update mode. Current State Display: Only a blank or frozen screen via HDMI (no visible output or error message). Input: Keyboard is detected (USB works), but no interaction is possible. Mouse is also connected via USB but not visible or responsive. Constraints No UART interface available for debugging or direct access. (no cable for the moment) Only HDMI output is available, but it’s not interactive or informative. Or SD Card Any proposal to unlock the situation Thanks in advance https://cdn.discordapp.com/attachments/1433426165988851843/1433426168165699685/image.png?ex=6904a5a6&is=69035426&hm=b52854a9e45270a5c271218023ce1ef3895ece9f04d4542f139626514a524ad4& https://cdn.discordapp.com/attachments/1433426165988851843/1433426168857497680/image.png?ex=6904a5a6&is=69035426&hm=a656317eea5eb5f97d87c6327c9c97ee7235acdd96ec6ad0c91905240c1c4bca& https://cdn.discordapp.com/attachments/1433426165988851843/1433426169994412134/image.png?ex=6904a5a6&is=69035426&hm=8d80304d07bda1aaca8f19843103b1f1b82f535a2fd7de250dca50ccb0ac4f8d&
