I was attempting to put OpenWRT on a TP-Link Festa F61. I messed up and wiped out the u-boot image. I am trying to build a new u-boot image and ymodem it there. Followed the exact steps here: https://docs.u-boot.org/en/stable/board/mediatek/mt7621.html.
When it boots I get this and it hangs: U-Boot 2025.07-00889-gbd0ade7d090a (Jul 22 2025 - 16:25:47 -0500) CPU: MediaTek MT7621A ver 1, eco 3 Boot: DDR3, SPI-NOR 3-Byte Addr Clock: CPU: 880MHz, DDR: 1200MT/s, Bus: 220MHz, XTAL: 40MHz Model: MediaTek MT7621 RFB (SPI-NOR) DRAM: Is this a newer version of the MT7621 that is not compatible? Maybe a different DRAM binary is needed? Here is a link with DMESG and boot logs - https://forum.openwrt.org/t/support-for-tp-link-festa-f61-v1-6/236744/3. TIA
