Ethernet Flash Boot Loader

Hi guys,

I just started to build an app on PE-HMI1 (SSP 1.2.1).

I want know if there are some example of BootLoader work on ethernet like the old RX62N/RX63N ( www.renesas.com/.../D3007836.html )

Somebody knows something already implemented.

Thank you.

Hi James,

Error code 701 means that the image is invalid. Did you prepare the image in BCH format using the Flashloader Utility?

Hi Adboc,

I have read though the bootloader and downloader examples. Is this project bootloader ? Do you have the downloader example ?

Hi James,

The Flashload Utility is a standalone PC application. One of its feature is a SREC to BCH converter. I suggest reading this application note: synergygallery.renesas.com/.../r11an0073eu0100-synergy-ssp-flashloader.pdf

It explains how to use the utility mentioned above.

Hello James,

The TFTP bootloader example works only with single-slot images that start at 0x40000 (256k mark).

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:

Hi JHJ,

We are developing an OTA bootloader, we have also faced the same error (701) while calling newImagePrepare api .
We use 2 slots for our project. We have solved the issue by referring the code shared by Karol.

We used only the sf_firmware_image _internal framework because the downloader framework follows the procedure for
the communication with flashloader utility.

So we have to handle each block separately as the code shared by Karol TFTP bootloader example.

Hi James,

if you have not changed the header location in your program, then try changing 40400 to 40800.
I recommend you to refer flashloader pdf for generation of BCH file and also linker script section.
