Hi All,
s7g2 (Custom Board)
SSP 1.7.0
e2Studio 7.8.0
We want to code flash our board for upgrades etc.
We have made provision to store any file(s) required for this to the SD-Card.
Please share any link(s) which can help us achieve this.
Few questions...
1. Which Files/Resources are required for the process which I need to transfer to the SD-Card? Is any Conversion etc required? our current Output file is a .Hex.
2. After which I will place the new code in a buffer and flash it... Any working examples?
Regards,
Surojit.
The current solution for Synergy is the Secure Boot Manager - Secure Boot Manager - Application Note - Renesas https://www.renesas.com/us/en/document/apn/secure-boot-manager-application-note
Your chip has a bootloader built in that can receive a flash image via USB or serial from a Renesas Flash PC tool.
The boot manger app will allow you to build a bootloader that will read your image from SD card, erase the existing app, write a new one, and jump to it.
You could use a hex file with s recs or other format. You might want to consider a secure bootloader that will only allow ot to flash image an signed image known to produced by you.
