Many people always ask this question, so here is a summary document for your reference. The following steps areLinuxSystem, not for wince. Maybe you will notice that there are far more people doing Linux research in embedded systems than those doing wince. Many manufacturers also provide information based on Linux. I have been hard to understand. In fact, the win
then run in SDRAM. As for the base address of flash why can be 2G, this is by the CPU and flash of the SPI bus special circuit connection way to decide, oh, the electronic origin should not be difficult to understand. Furthermore, some chips also raise external pin pins to add an offset (such as 1M) to the address line, so two processors can use a different part of the same flash (0~1m,1~2m), and the interior only feels like it starts with a 2G address. The following key question is, what is

From: Shanghai Shangguan embedded training http://www.uplooking.sh.cn/embedded_training/tecnews/ARM/2013/0226/2210.html When processing real-time collected and updated data, the data update speed does not match the data processing speed. In this case, data loss may result in inaccurate data processing results and even unpredictable consequences. Therefore, a mechanism is required to coordinate data update and data processing, this ensures data integr

Using the GdB method debugging, because of the limited resources of embedded system, it can not be debugged directly on the target system, which is usually debugged by Gdb+gdbserver. The target system must include the Gdbserver program, and the host must also install the GDB program. Here we are not directly using the Linux distribution with GDB, need to cross compile gdb and gdbserver. A Objective
