测试版，遇到问题请到 issue 反馈，或者直接使用稳定版本固件

New Features

• Boot LOGO will be different in USB upgrade mode and normal boot.
• image.Image() support bg arg to set background or clear memory(memset)( by default we not clear memory for faster initialize, if you encounter random background content, you shoud set bg arg).
• add IMU AHRS support, refer to APP and documentation
• maix protocol support disable and add uart port selection for maix comm protocol, so now you can select default maix protocol uart in settings APP.
• Camera support set buff_num=1 to get image with lower latency, refer to documentation.
• Camera support disable AWB and mannually set WB gain, refer to documentation
• fs add File.sync API
• Add USB audio driver support.

Optimization

• Optimize APP bootup speed on MaixCAM power on, faster 2~5s.
• Toolchain memcpy support RVV acceleration, so many copy ops may faster likeimg.copy() etc.
• New system settings config file at /boot/configs.
• optmize some basic API like log,memory_info,fs.join
• change adc pin arg to id
• fix speech and optimize startup speed

BUG Fix

• OS04A10 90fps mode spend too much CPU power, due to lower than 90fps, now lower down to 80fps.
• fix os04a10 causing system freeze
• fix get_pixel RGB888 get wrong int data bug
• fix image.load png bug
• fix sys.memory_info overflow bug
• fix: correct parameter order in Modbus read functions
• 修复了 开机有几率启动失败卡死在开机界面的问题 以及MaixCAM-Pro开机后功率太大会重启问题，以及有概率无法充电的问题。
• 相比 v4.11.6 修复了 人脸关键点 手关键点检测无法运行的问题

APP update

• Increase the bottom margin of the image list to avoid the last line of images being obscured (when long pressed to delete)
• add maix default comm protocol for apps
