c6678 uart nor

hi,
我用的是tmdsevm6678le评估板，仿真器xds560，在跑ti\pdk_C6678_1_1_2_5\packages\ti\platform\evmc6678l\platform_test时，其他均正常，只有uart和nor失败，详情如下

nor:

[C66xx_0] Current core id is 0
[C66xx_0] EEPROM test start
[C66xx_0] test_eeprom: passed
[C66xx_0] EEPROM test complete
[C66xx_0] NAND test start
[C66xx_0] test_nand: passed
[C66xx_0] NAND test complete
[C66xx_0] NOR test start
[C66xx_0] test_nor: Read failed errno = 0x2
[C66xx_0] NOR test complete

uart:

[C66xx_0] Current core id is 0
[C66xx_0] UART test start
[C66xx_0] Open a serial port console in a PC connected to
[C66xx_0] the board using UART and set its baudrate to 115200
[C66xx_0] You should see following message ---
[C66xx_0] This is a Platform UART API unit test ...
[C66xx_0] Type 10 characters in serial console

于是我把程序换成论坛上提供的测试程序KI_STK_20140123，中的uart，还是失败，具体现象如下：

[C66xx_0] Initialize DSP main clock = 100.00MHz/1x10 = 1000MHz
[C66xx_0]

在尝试打印字符后，就卡住了，我的串口上位机程序也没有反应，当然我的串口线已经连上，com1打开，波特率也设成了115200，请问是我的配置哪里有问题吗？还是买来的板子uart模块有问题？另外，nor flash通过spi驱动，所以我尝试运行KI_STK_20140123，中的spi，运行仍然失败，请教下是哪里有问题，会是nor flash芯片的原因吗？
[C66xx_0] Initialize DSP main clock = 100.00MHz/1x10 = 1000MHz

[C66xx_0] SPI loopback test passed with data pattern 0x5555. Throughput= 32Mbps
[C66xx_0] SPI interrupt test: manually generate RX overrun error...

另外我在跑KI_STK_20140123的程序时都是不能单步执行的，显示如下：
No source available for "main() at SPI\Debug\SPI.out:{3} 0xc06aa84{4}"
请问是需要在哪里设置吗？
总结下我的问题：
1.uart配置哪里有问题？还是说板子uart模块有问题？
2.spi驱动nor flash，代码运行失败，会是哪里的问题？
3.KI_STK_20140123的程序不能单步执行，是哪里设置有问题？
菜鸟提问，各位大神多多指教

1，你去下一个最新的MCSDK，运行一下POST工程看看有没有问题C:\ti\mcsdk_2_01_02_06\tools\post，当然先要验证你的PC串口OK，EVM上有个跳线控制UART是走USB或者串口针，你看看跳线是否正确；

2，还是上面那样，保证BOOT mode设置到NO BOOT，按照C:\ti\mcsdk_2_01_02_06\tools\post\docs的步骤运行POST看看，

3， STK不能单步是因为打开了优化，在编译菜单里关闭优化重编译即可。

hi Allen Yin,

首先非常感谢你的回答，你说的很对，我尝试改变跳线的连接后，串口已经可以正常调通了，我会按照你说的去下载一个最新的mcsdk，然后继续尝试，如果有新的进展会更新在这里，谢谢

hi,
你是对的，我确实在ti\mcsdk_2_01_02_05\tools\writer\nor找到了一个nor操作的示例

代码，可以正常运行，我对比了下D:\ti\pdk_C6678_1_1_2_5\packages\ti\platform

\evmc6678l\platform_test的项目，发现是在malloc时出现了问题，应该是我设置的内存

太小，请问怎么能加大内存？请多多指点，我的cmd文件内容如下：

malloc使用的是堆上的memory，如果不够，应增加-heap的值
