6670各种引导方式总结，请大家关注，帮忙汇总经验、方法

现已实现网口的多核程序引导，具体过程参考附件中内容。

但现在通过将多个.out文件烧写到nand/nor flash中进行多核引导还是不行，请专家进行讲解，如何将多个.out文件合并下载到flash中，并实现每个核加载一个.out文件分别进行相关应用操作。

谢谢！！！

可以参考一下论坛上过去的帖子：

Hi, Andy Yin:

Thank you so much for your help. However, according to your guide, I still cannot work it out. To make the question described more easily, let me tell you about my work on it. The main core execute the main initiation and after unlock kick0 and kick1 it gives IPC to the other cores, and then put 0x00820000（ _c_int00 address） to 0x008ffffc（magic address for 6670） in order to tell the other cores where to start to execute. The other cores get the IPC and change their PC to 0x00820000 and start their own tasks. Therefore, I have 4 .out files which are core0.out, core1.out, core2.out and core3.out, respectively. I want to use NAND flash to realize 2nd boot. I have already write IBL（i2crom_0x51_c6670_le.bin） into EEPROM and use i2cconfig.gel to configure IBL. Now I have trouble with the format which should be written into NAND FLASH. I have tried to use
1. hex6x.exe to change each .out file into .btbl file.
2. mergebtbl.exe to merge the 4 .btbl files into 1 .btbl file.
3. bconvert64x.exe to change format using -le.
4. b2i2c.exe multicore.btbl.be multicore.btbl.be.i2c
5. b2ccs.exe multicore.btbl.be.i2c multicore.btbl.be.i2c.ccs
6. myparser.exe multicore.btbl.be.i2c.ccs i2cconfig.txt i2c.ccs

I have written every format into NAND FLASH but none of them could work. Please tell me in detail how to change the 4 .out files into one file being written into NAND FLASH which can work well. Thank you so much.

Hi Andy Yin:

我已实现网口多核引导，FLASH引导实现单.out 文件中断式多核引导，即将所有核的应用全部放在一个工程中用coreID区分进行工作。

但是在进行中断时出现了问题，我试图将多核中断加载到我的TCP/IP LOOPBACK 工程中，主函数调用多核应用选择函数，利用主核给其他核发中断，启动其他核进行工作，但是在我的工程运行过程中不知什么原因始终在选择函数中循环操作无法跳出，即主核不断重复运行选择函数段，导致应用程序无法进行下去。

附件中是我的工程的简化版，请各位专家大牛帮忙。

你好，你说的flash是指EMIF16接口的nand flash吗？

是的，请问您有什么高见，请不吝赐教！

我将程序中选择函数部分中

printf("\r\n\r\nLED_Multicore_Test is Done!\r\n\r\n"); 

platform_write("\r\n\r\nLED_Multicore_Test is Done!\r\n\r\n");

两句去掉改为用uart_write输出程序即正常工作了。

另外我在主函数中加了核的ID判断，让主核跑TCP/IP程序，其他核在选择函数中进行应用跳转去执行其他的应用。在本例中，只是其他核分别闪了5次灯后IDLE。

接下来还剩下的问题就是如何用NAND FLASH 实现多个.out文件的整合烧写并成功进行引导。

请各位专家不吝赐教，各位DSP学习者提供宝贵的建议和经验！！！十分感谢！！！

我是刚开始做这个启动，有问题还得多请教您

请问楼主，你的第3个问题，flush的多核加载问题解决了么？我也遇到这个问题了，还请解惑！
