Ethernet Flash Boot Loader

Hello Microit,

I developed a simple bootloader application for SK-S7 that uses Ethernet to connect to the TFTP server at 192.168.0.2 (I used TFTPD64 on Windows to host files) and download and program "S7_SK_image.bch". Project was developed for SSP 1.2.0-b.1 and older version of the Flashloader framework but should work with the new modules without any problem.

Hi Karol.

I have a question about the downloader part, the downloader framework does not provide the TFTP communication option.

Can you provide example how to set it up ?

I'm very confused. The whole OTA updated project has 2 parts as the example provided from the https://synergygallery.renesas.com/ssp/utility#read.

Hi James,

The project Karol shared (TFTP boot) does not use the downloader framework. The "downloader" part can be found in Client Thread - it contains an instance of the NetX TFTP Client module. The image is downloaded and written to the device in src/client_thread_entry.c file.

The project can be imported into e2 Studio or IAR, here is the guide how to import the Synergy project:
