X6512 Flash File Apr 2026

Use the partial‑program feature of the bootloader: send a small *.bin that contains the new config and the address offset. The bootloader will erase only the sector containing the config and rewrite it.

# Program a .x65 container xflashprog -p /dev/ttyUSB0 write -f firmware.x65 -a 0x0 x6512 flash file

Typical causes: wrong vector table address, missing reset handler, or watchdog not cleared early enough. Verify that the first word of the image contains the correct initial SP and that the second word points to a valid Reset_Handler . 10. Sample End‑to‑End Workflow (CI/CD Integration) # .github/workflows/flash.yml name: Build & Flash X6512 Firmware on: push: branches: [ main ] Use the partial‑program feature of the bootloader: send

# 1️⃣ Compile - name: Build firmware run: | make clean all arm-none-eabi-objcopy -O binary build/app.elf build/app.bin Verify that the first word of the image

# Optionally convert to .x65 x65wrap -i backup.bin -o backup.x65 | Method | Typical Tools | Steps | |--------|---------------|-------| | Standalone ISP programmer | XFlashProg , FlashCatUSB , Segger J-Link (with flash driver) | 1. Connect programmer to the SPI pins (CS, SCK, MOSI, MISO). 2. Load .bin / .x65 in the GUI or CLI. 3. Verify/Erase/Program. | | Bootloader‑based update | XBootloader (UART, USB, CAN), custom bootloader firmware | 1. Put device in bootloader mode (e.g., pull BOOT0 low, send “0x55” over UART). 2. Transfer the flash file using XModem/YMODEM or a custom protocol. 3. Bootloader validates CRC and flashes. | | In‑system (via MCU) | HAL HAL_FLASH_Program() , X6512_Prog() API | 1. Load the binary into RAM (e.g., via UART). 2. Call the flash‑write routine sector‑by‑sector. 3. Optionally verify with HAL_FLASH_Program() return status. | Example: Flashing via XFlashProg (CLI) # Erase the entire chip first xflashprog -p /dev/ttyUSB0 erase

All tools are command‑line friendly, which makes it easy to integrate them into a CI/CD pipeline for automated builds. | ✅ Checklist Item | Why It Matters | |-------------------|----------------| | Validate the binary size – ensure it does not exceed the target flash capacity. | Prevents truncated code and “out‑of‑bounds” writes. | | Run a CRC‑32/MD5 hash on the file – compare with the hash supplied by version control. | Detects accidental corruption. | | Backup current flash – read the existing content to a file before overwriting. | Allows rollback if the new firmware misbehaves. | | Confirm erase‑write cycle count – many flash parts have a spec of ~100 k cycles. | Avoid premature wear. | | Check power rails – 3.3 V ±5 % and ground stability. | Guarantees reliable programming. | | Set proper write‑protect pins – disable WP before flashing, re‑enable after if needed. | Prevents accidental writes in production devices. | | Test on a “golden unit” – flash a known‑good board first. | Catches layout or pin‑mapping errors before a batch. | 9. Frequently Asked Questions (FAQ) Q1 – Can I use a .hex file directly with XFlashProg? Yes. XFlashProg auto‑detects Intel HEX and converts it to raw binary before sending data to the device.
