我的系統使用AM3358串口啟動方式啟動,但是在串口中只收到5個C收然後就收不到了,然後再過一會兒又收到5個C,如此重複,請教下是什麽問題?
我的SYSPIN順序是
LCD0 LCD1 LCD2 LCD3 LCD4 LCD5 LCD6 LCD7 LCD8 LCD9 LCD10 LCD11 LCD12 LCD13 LCD14 LCD15

这个现象是正常的,说明rom code已经初始化了串口,开始发送可以启动的信息,你可以通过串口x modem发启动的image过去
我是用串口x modem 發啟動image過去,只是沒有反應,所以我就懷疑是不是硬件有問題,正確的串口啟動,不是一直發C的嗎?
硬件的復位腳B15(PROZ)、A10(NRESETIN_OUT)、B5([RTC_PORZ)我都查過了,就是上點的時候變了一下,後面就一直沒變化了。
我的板子沒有一直發C,但是我們公司的軟件工程師告訴我,正確的應該要一直發C,那正確的串口啟動,應該是怎麼樣的?
是一直發C,還是發一下又不發循環這樣的嗎?
For EVM Starter-Kit (EVM-SK) board
The micro USB port (Jumper P3) has to be connected to the host. Please make sure that the Virtual COM Port driver is installed. The driver is available here for downloading. This micro USB-to-serial connection is used for displaying messages on the serial console of the host, provided the port is properly selected.
A serial terminal application (like Tera Term / HyperTerminal / Minicom) should be running on the host.
The host serial port is configured at 115200 baud, no parity, 1 stop bit and no flow control.
Ethernet port(s) on board connected to port(s) on the LAN.
A microSD card is required. MMC/SD booting on EVM-SK board essentially means booting via a microSD card.
下载了CDM v2.08.30 WHQL Certified.exe安装后,还是找不到串口?不知道如何使用虚拟串口?能否尽快帮忙解决下?不胜感激
这个sk的板子,上电后,要按下SW5上电才可以让这个串口工作的
