Rs485怎么引导加载程序UDB UART

嗨，大家好，
我需要为一个PSoC 4模块写一个RS485引导加载程序，我想知道是否有可能在没有“定制”任何东西的情况下做到这一点。事实上，在PSoC 4中使用“Bootloader”组件与UDB UART导致不正确的引导加载，但是使用SCB UART，RS485通信似乎并不直接实现（在UDB上，您拥有有用的“硬件TX使能”特性）。我正在测试通过使用“UART Bootloader主机应用程序”从AN6262在CY8CITK-042-BLE先驱与PSoC 4 BLE模块通过USB和每个引导加载尝试导致“BootLoad失败与错误代码：0x000”A。使用相同配置的SCB引导加载工作良好。我应该编写自己的引导加载程序还是我正在使用的组件、模块和软件出错？
我已经附加了工作区。
谢谢您！

  Hi all,

I need to write a Rs485 bootloader application for PSOC 4 module and I would like to know if it is possible to do that without "customizing" anything. In fact seems that using "Bootloader" component with UDB UART in PSOC 4 leads to uncorrect bootloading but with SCB UART an RS485 communication seems to be not straightforward to implement (on UDB you have the useful "Hardware TX Enable" feature). I'm testing the application using "UART Bootloader Host Application" from AN68272 on CY8CKIT-042-BLE Pioneer with PSOC 4 BLE Module through USB and every bootloading attempt leads to " Bootload Failed with Error Code: 0x0000A". SCB bootloading with the same configuration is working well. Am I supposed to write my own bootloader or am I doing something wrong with the components, modules and softwares that I'm using?

I've attached the workspace.
Thank you!

Simone
