As more and more component manufacturers switch to the YTM32B1 platform, the mass production process commonly encounters pain points such as slow adaptation of domestic automotive chip burning algorithms, complex ECC storage partition operations, cumbersome option byte configuration, poor anti-interference ability of CAN FD electronic control board long line probe burning, safety bit configuration, batch writing of traceability codes, and insufficient offline burning stability. In response to the urgent needs of domestic automotive electronics solution providers, SMT automotive production lines, and component factories, MaxWiz has completed exclusive programming algorithms, firmware, and upper computer software upgrades. The entire series of programmers has officially added Yuntu YTM32B1 series chip programming support, connecting the entire process of research and development debugging, sample verification, small batch trial production, and automated automotive production lines, while balancing the flexibility of development and debugging with the strict safety and traceability requirements of automotive production.
Yuntu YTM32B1 series burning core capability
1. Stable burning of SWD interface, adapted to ECC multi partition architecture. Based on the standard SWD debugging interface, developed a deep optimized exclusive burning algorithm, adapted to YTM32B1 series PFlash, DFlash, and RAM partition architectures with ECC; Support whole chip erasure, partition independent erasure, firmware burning, data area separate burning, and CRC verification after burning; Perform timing and anti-interference optimization for scenarios such as long line probes, fixtures, on-board testing points, and bare burning of burning seats on vehicle boards, to reduce the defect rate of vehicle body boards and sensor boards during board burning, and adapt to common isolation fixtures and multi board burning conditions in automotive production lines.
2. Visualization options byte, startup parameters, and protection bit configuration support visualization configuration of YTM32B1 BOOT startup selection, clock configuration, BOR power down detection, hardware watchdog, IO function configuration, Flash write protection, debugging access permissions, and other parameters; Configuration items can be packaged and saved as engineering files with firmware, which can be uniformly called by the production line to avoid the risk of electronic control batch caused by manual configuration differences and reduce trial production accidents of automotive products.
3. Flexible control of serial number SN, VIN code, calibration parameters, and version information. Burning supports fixed codes, incremental serial numbers, scanning and issuing SN, CSV batch import of unique codes, and can write the vehicle VIN, hardware calibration parameters, version number, and batch information at the specified DFlash address; Support burning count locking, control the number of times a single chip is burned, prevent repeated burning and mixing of defective products, meet the requirements of one item, one code, and full traceability for car components, and adapt to seats BMS、 The production requirement for writing calibration parameters separately to the sensor module.
4. Support for security configuration, read protection, and encryption functions, safeguard domestic electronic control intellectual property rights, support debugging port locking, Flash read protection, and code protection configuration. Combined with the chip's built-in AES/SM4 security engine, firmware writing and security locking can be completed in one step during the burning process to prevent firmware from being read or reverse cracked, protect AUTOSAR underlying, control algorithms, and other core assets, and meet the requirements of in vehicle information security control.
5. Dual mode of online debugging and offline mass production
·Online mode: Operated by the upper computer of the computer, suitable for repeatedly downloading firmware, debugging CAN FD communication, timers, security configuration, ECC storage verification during the research and development stage, facilitating engineers to quickly iterate electronic control software;
·Offline mass production mode: The complete project is downloaded to the burner in advance and runs independently without a computer. It supports scan code triggering and one click burning, and the production line workstation does not require a matching computer. The operation is simple and controllable, suitable for large-scale production in car parts factories.
Advantages of Mass Production Burning Solution Matching with MaxWiz
1. Mainstream models are fully covered, and old users can upgrade and use the MaxWiz car standard universal programmer, which is compatible with YTM32B1 (L/M sub series). Old customers do not need to replace hardware, only upgrade the upper computer software and firmware to unlock the chip support, reducing the cost of adding hardware to the domestic car chip project production line.
2. Multi channel independent parallel burning, improving the rhythm of the vehicle electronic control production line, supporting multi-channel independent parallel burning. Multiple YTM32B1 are synchronously burned at multiple workstations on one host, and each channel is independently verified. Single channel defects do not affect the continued production of other workstations; Suitable for batch burning of multi panel and multi module vehicle control boards, improving production line throughput efficiency and adapting to Tier 1 large-scale order production.
3. Deep integration with automated production lines, with logs that meet vehicle regulations for traceability and auditing. Support for scanning code guns to trigger burning, local storage and uploading of burning logs to MES systems, defect labeling, and production data statistics; The log includes chip UID, SN code, burning time, firmware version, verification result, and workstation number; It can be connected to robotic arms, ATE test benches, and automatic testing fixtures, integrated into fully automated SMT production lines to achieve unmanned burning and full process traceability, meeting the audit requirements of the automotive parts industry.
4. Engineering file encryption management, continuously expanding model support firmware, partition configuration, security parameters, SN rules, and calibration parameters packaged as independent engineering files. Engineering files support encryption to prevent configuration leakage; Directly call across devices and factories; In the future, YTM32B1 will add new sub models, and MaxWiz will continue to expand its support list through software firmware iteration to quickly respond to new project selection.
5. Provide exclusive technical support for domestic car cores, including YTM32B1 burning project templates, wiring references, tooling design guidelines, ECC partition operation guidelines, and common problem manuals; The technical team can assist customers in debugging isolation fixtures, solving production difficulties such as unstable long-term burning, option byte configuration, safety bit unlocking and locking, batch calibration parameter burning, etc., and cooperate with customers to complete production line trial verification.
From the debugging of electronic control algorithms and CAN FD communication verification in the research and development stage, to small-scale trial production verification of yield and functional safety testing, and then to large-scale automated mass production, MaxWiz provides a stable, efficient, and traceable chip programming solution for the YTM32B1 domestic automotive MCU project, solving pain points such as long adaptation cycles, complex ECC partition operations, difficult mass production traceability, and unstable long-term burning, and helping domestic automotive electronic control solutions quickly land and smoothly achieve targeted mass production.
