hello I'm new to the OPENWRT world, my report and experience with openwrt and a mikrotik rb760igs, it happens that I have no experience with linux and codes in the terminal and I chose to install via Tiny PXE through windows because it is more comfortable for me, as the Wiki guides of the product, my Mikrotik does not enter the moto tftp, I connect it holding the reset button and nothing appears, I do not see it sending the file and after a while the beep occurs and it starts with RouterOS normally, any help? (OBS I am Brazilian and sorry for the English)
