Thank you for sharing the U-BOOT image. I uploaded the image to FLASH memory, version KL25L12835F is not available on the market and I replaced it with MX25L12835F, these are the same chips. The router starts and I can upload the firmware using the web page, previously stopping the start of the software using the smoother through the TTL terminal using RS232.
Frimware loads the system after the restart starts, Wifi works because you can see SSID. However, there is a problem as I want to go to the router’s configuration page. After entering the ip address of the router, 503 appears in the browser. From what I noticed there is no U-BOT env partition (64KB) and factory partition (64KB), I was hoping that the firmware will create them. Is there any chance for someone to share bin images of these partitions?
