用户ISP程序升级问题
我在使用了官方的用户ISP升级程序后，升级的文件为一个官方的USB-HID范例，发现地址偏移后使用USB-HID不能正常使用了如和解决
针对您在使用官方用户ISP升级程序后，USB-HID范例因地址偏移导致功能异常的问题，建议采取以下步骤进行排查与解决：<br><br>1. 地址偏移确认：首先，请确认升级文件的地址偏移是否与目标设备的存储器布局匹配。建议查阅设备的技术手册，核实USB-HID范例的起始地址及存储区域是否正确。<br><br>2. 固件校验：使用官方提供的校验工具，对升级后的固件进行完整性检查，确保固件未在传输或写入过程中发生损坏。<br><br>3. 调试信息获取：通过调试接口或日志功能，获取USB-HID初始化及运行时的详细信息，分析是否存在地址访问错误或其他异常。<br><br>4. 固件回滚：如问题持续存在，建议回滚至升级前的固件版本，验证是否为升级文件本身存在问题。<br><br>5. 技术支持：若上述步骤无法解决问题，请提供详细的升级步骤、设备型号及错误信息，联系官方技术支持团队进行进一步诊断与修复。<br><br>通过系统化排查，可有效定位并解决地址偏移导致的USB-HID功能异常问题。<br><br>[本文内容由国芯人工智能辅助生成，仅供参考] 直接用这个可以的，如果地址不对是烧入不上APP1的，现在是可以烧入自己的app1程序但是功能不对
用的就是官方的USB升级工具
是不是带USB-HID的程序地址不能偏移 使用的是这个范例，可以正常使用，但是把升级文件换成我的程序（USB-HID），自己的程序就跑不通 使用的是哪个型号？使用的ISP工程和APP工程可以发一下看看 cdx 发表于 2025-3-21 09:56
是不是带USB-HID的程序地址不能偏移
如果用的8H型号，除了偏移程序地址，还要偏移中断
