Security Advisory Report: Ergo R0516 Firmware

Report Date: October 26, 2023 Subject: Security Vulnerabilities in Ergo R0516 Firmware Status: Public Disclosure / End-of-Life (EOL) Notice ergo r0516 firmware

6.2 Rollback Protection

• Two firmware slots: active and update.
• A flag byte indicates which slot to boot.
• If new firmware fails to start (watchdog reset within 5 seconds), bootloader reverts to previous.

4. Communication Protocols in R0516

Common Ergo R0516 Firmware Errors and Fixes

Even with careful planning, issues can arise. Here are the most frequent problems: Security Advisory Report: Ergo R0516 Firmware Report Date:

6.1 Update Protocol

1. Host sends ERGO_UPDATE_START command over CAN or UART.
2. Bootloader responds with ACK and waits for binary chunks (256 bytes each).
3. Each chunk includes a sequence number and CRC.
4. After last chunk, bootloader verifies overall SHA-256 hash.
5. On success, bootloader marks new firmware valid and resets.

8.1 Attack Surface

• Debug interface – Often left enabled on older R0516 units (SWD can read full flash).
• Update channel – No authentication; man-in-the-middle can inject malicious firmware.
• Config EEPROM – I2C bus exposed; could be externally modified to change I/O behavior.
