Hi, @Rathesh1. Rathesh1: i uploaded firmware as flash programming Did you use the ISP program when uploading firmware? If you did not check the ‘Erase all code block’ option, the data area of memory may have been cleared. First, connect the device using the USB type B cable and check the debug message. and you can refer below link. WIZ750SR Recovery User guide Thank you.

Hi rena, I took source code from following link of v1.2.4 GitHub Releases · Wiznet/WIZ750SR WIZnet Serial to Ethernet(S2E) module based on W7500 chip, WIZ107/108SR S2E compatible device - Wiznet/WIZ750SR Compiled this code in Keil without any changes in source code. I updated firmware using config tool. For updation I used binary file “W7500x_S2E_App.bin” from “WIZ750SR-1.2.4\WIZ750SR-1.2.4\Projects\S2E_App\bin” path. I found same issue. So I again updated file using config tool with binary file “WIZ750SR-1xxv124.bin”. Then it is working fine. Means I only updating App part. So there is no requirement of WIZISP. It is not working only when I complied source code and using this binary file. Is there any issue with source code or starting address? Starting address of IROM1 is 0x7000 and IRAM1 is 0x20000000. Please help. Thanks and regards, Swapnil
