请问，版主：

am1808的pru实现的softuart的奇偶校验问题解决了吗？

这个wiki上说是支持的：

Features

The Soft-UART implementation supports the following features:

6 – 8 bits per character (configurable)
LSB-first
1 or 2 stop bits
Receiver oversampling of x8 and x16 (configurable)
Parity generation and error detection (even, odd, or no parity)
Configurable FIFO depth from 1 to 16
Configurable FIFO timeout
Configurable McASP serializer mapping for each TX & RX signal
Configurable half or full duplex
Independent baud rates supported for Soft-UART ports
- Configurable maximum baud rate (up to 115200 baud)
- Dependent baud rate for each Soft-UART based upon software-configurable maximum baud rate divided by 1, 2, 4, 6, 12, 16, 24, 48, 64, 96, 192, & 384
Two – four full duplex Soft-UARTS per PRU
- NOTE: The number of UARTs supported depends on software configuration options and baud rate of each UART. Refer to the Calculating Number of Supported Soft-UARTs and Soft-UART Configuration Options sections for additional details.

上面的连接是ti的TI E2E Community 关于pru uart的奇偶检验问题:2. Parity is a planned addition for 4Q.

支持。

谢谢，请给点资料吧

自己搞定了，什么事还是靠自己才有谱！

回复 Haohua Qin:

你好

为什么我移植后的 PRU suart 只能写数据，而不能读取数据呢？

回复 Haohua Qin:

你好，直接拷贝那个内核就好了嘛，看ti上说还要firmware和openembed,那两个不需要吗

请教am1808的pru实现的softuart的奇偶校验问题！
