PIC24FJ256GA106 UART引导加载程序问题

您好，我从微芯片下载了Bootloader示例项目。我已经编辑了一个硬件初始化文件以与MyPIC24FJ256GA106一起工作。我已经将引导加载程序加载到MyPIC24FJ256GA106上。这一切都工作得很好。我采用了led的示例项目，并将其加载到我的PIC24FJ256GA106上，它也工作得很好。当我尝试执行引导加载时，总会出现错误“引导加载超时：发现/握手失败，在指定的超时（xxxms）之前，没有收到响应“#”设备查询命令的命令确认”。但是，从通信通道接收到y个字节“我想这是因为我的引导加载程序没有正确地回复，并且我设置UART不正确。我没有对示例led项目进行任何更改，我只编辑了ex_uart项目，以使用myPIC24FJ256GA106进行适当的配置。我主要调用UART_INIT，并更改了UART_Reset的管脚。我正在附加一个带有UART设置的文件（我还将UART_MODULE_NUM设置为1）。有人能发现问题吗？

    Hello,

I have downloaded the bootloader example projects from Microchip here. I have edited one of the hardware initalization files to work with my PIC24FJ256GA106. I have loaded the bootloader onto my PIC24FJ256GA106. This all works fine.

I have taken the led example project and loaded this onto my PIC24FJ256GA106 and it works fine as well. My issue come when I try to do a bootload I always get the error "Timeout on bootload: discovery/handshake failure, did not receive command acknowledgement in response to '#' device query command before the specified timeout (xxxms). However, y bytes were received from the communications channel"

I assume this is because my bootloader is not replying properly and that I have set up the UART incorrectly. I have not made any changes to the example led project, I have only edited the ex_uart project to have a "proper" configuration with my PIC24FJ256GA106. In main I call UART_INIT and I changed the pins for UART_Reset.

I am attaching a file with my UART setup (I also set the UART_MODULE_NUM to 1 as well).

Can anyone spot any issues?
