vgaggia Posted February 10, 2022 Share Posted February 10, 2022 So i've been trying to flash a firmware.bin with the sd card, but it seems that the board refuses to read the sd card, is there anything i can do, this is a brand new board(literally like 2 days old), the LCD also says printer disconnected for some reason The board is a Bigtreetech SKR 2, the LCD is a Bigtreetech TFT35 v3.0, i'm using Bigtreetech Stepstick Mute TMC2208 V3.08 drivers and a stock ender 5 plus power supply. The SD Card i'm using is a netac 8gb microsd card, i've tried using pre-compiled firmwares and i've tried compiling my own, nothing works, if the board is defective, how do i go about getting a replacement, i live in south africa so obviously shipping is quite expensive. I also emailed support but it seems that this is probably a better and easier way to get help Another noteworthy mention is that if i insert the sd card, power cycle, the firmware does not turn from firmware.bin to firmware.cur like everyone says it should, the board is working as i can connect to it with octoprint, if theres another way to flash it maybe with my pi/arduino i'd be down to try something like that too Quote Link to comment Share on other sites More sharing options...
BTT Tony Posted February 11, 2022 Share Posted February 11, 2022 Hi， 1. First format the SD card and select FAT32 as the file system. 2. Please put two same firmware in SD card. One named "firmware" and one named "firmware.bin". 3. Then re-update the firmware. Check to see if any of the files on the SD card can be capitalized. Because some win10 systems hide the .bin suffix by default. It maybe mater to your firmware. Please make a test with the attachment firmware. firmware.bin Quote Link to comment Share on other sites More sharing options...
vgaggia Posted February 11, 2022 Author Share Posted February 11, 2022 (edited) Ok so i followed your instructions exactly, still not working, since octoprint works i tried loading a gcode model onto the sd card and that's not even showing up, the sd card works with my stock ender 5 board, so i think the sd card reader on my SK2 has to be broken, i don't see what else it could be since my computer sees it, and the old board see's it too. No file names changed in any way after looking at the sd card afterwards On octoprint i'm getting SD Init Fail as well whenever i connect to the printer EDIT: Is there nothing i can do perhaps to flash it another way I.E using an arduino or usb or octoprint maybe?
