rickleaf请进，ecos的ROM RAM启动方式在cortex-m3上应该如何理解？
本帖最后由 wangle315065 于 2012-10-18 11:01 编辑在网上搜索了各种关于ecos移植方面的资料，还是搞不大清楚，ecos的各种启动方式是怎么回事，请高手解惑。
另外GDB是调试程序工具，rickleaf大侠的windows下如何通过gdb连接redboot调试eCos 中，
是先ROM烧写redboot，在RAM格式的ecos应用程序，进行调试，烧写redboot是否还要借助于jlink之类的下载工具，在UBUNTU下应该怎样呢？ 等待讲课！ 热切盼望各位大牛进来传道授业。 顶一下，手头有一个一年前买的openjtag，先试试在ubuntu下用openocd，看能不能链接上。 openocd.cfg改成这样
telnet_port 4444
gdb_port 3333
gdb_memory_map enable
gdb_flash_program enable
interface ft2232
ft2232_vid_pid 0x1457 0x5118
ft2232_layout "jtagkey_prototype_v1"
reset_config trst_and_srst
source
在使用openocd时出现这样的输出,此时没有把板子和openocd链接在一起。
查看openocd是支持LPC1768的。

这个情况是不是因为没有查板子，所以GDB等待不到ack信号。。。。。。jtag和板子的接口对不上号，解决ing 再顶。

这个是不是说明openocd的tcp口和pc的链接，openocd的usb口和openjtag的链接通了？

有没有对openocd熟悉的大牛，进来指点下，我想通过openocd把程序直接烧写到SDRAM上，或者是烧写到NANDFLASH上，应该怎么做？
我的板子是IAR的LPC1788olime版。 有ECOS资料的网站吗 ecos资料不是很多，我在csdn和官网上找资料，附个我的ecos相关的书签。

大牛的意思是给我些ecos资料的网站，还是问我有没有ecos资料的网站额。偶愚钝。。。
