加密版c6748串口引导问题

Other Parts Discussed in Thread: OMAP-L138

现在同一块电路板一个用c6748非加密板，一个用加密板，非加密板可正常引导，加密板却引导不了，都是同一个.out文件，只是非加密版用AISgen for d800k008 生成bin文件，引导用UART Boot host，一个用SecureHexAIS_OMAP-L138生成bin文件，引导用GenericSecureUartHost，为什么？下面是非加密版配置文件和引导结果：

一直是Waiting for DONE...，是加密版的ini文件有问题吗

你试试这个ini文件。你是就打算用加密版的芯片，还是只是因为买错了，要解开JTAG来用一下而已？TI不建议用户在加密版权的芯片做开发调查试，这样比较麻烦。

是供应商发错了，发了加密版，结果用JTAG写入不了程序，并且用原先生成的非加密ASI bin文件应该也用不了，这个加密版的芯片也是必须要加密才能用，用你这个ini文件，里面需要key_hdr_sha256_enc.bin，这个key_hdr_sha256_enc.bin文件是在哪里呢，现在生成不了AIS bin文件，注释掉genKeyHeaderFileName=key_hdr_sha256_enc.bin后可以生成AIS bin文件，但是引导不了

TI__Guru 64206 points

突然想起来一件事，你的.out是DSP的还是ARM的，加密版的芯片是先从DSP启动，也就是说要dsp的.out文件。试试先~~~

另外我建议你找你的供应商商量一下，看能不能换货，毕竟这不是你最终要用的芯片。

我手头也没有加密版本的开发板，很多问题只能看文档来回答，没条件测试。

.out是DSP程序，以前用的是tms320c6748BZWT,这次供应商发的是tms320c6748BZWT E,由于没注意都贴片到板子上了，由于解不密，无法连接JTAG，写入不了程序。

你试试这个文件看能不能下载，把JTAG unlock。

这种unlock都是一次有效的，断电后又lock了，如果只是想试试这个功能可以。

请问你生成这个bin文件的 ini 文件是怎样的，.out文件是怎样的，有代码吗，我解锁后可以连上仿真器，但是装入NANDWriter_DSP.out程序后还是写入不了我原先程序非加密的bin，也无法调试，执行不了go main

我现在的目的就是能够通过JTAG运行NANDWriter_DSP.out，写入我以前的程序，并且断电后可以从NAND FLASH正常运行，请问我该怎么做

如何联系你呢，深圳有你们的工程师能解决下吗

按说unlock 后就可以当做普通芯片使用了，这时可以用普通的nand writer把加密版的bin写进去。

通过JTAG访问其它寄存器正常吗？

有加gel 文件初始化DDR， PLL等吗？

你可以通过你的供应商找到TI的支持。

通过8562.dsp_sectononsec.bin引导解锁后可以连接JTAG，但是点connect后（我现在用的是CCS3.3），不能很快连上，
过了几分钟,提示：
The GEL callback "OnTargetConnect()" for the target "OMAPL138_TIXDS560/C6400PLUS_0" is still processing.
The function could contain an inifinite loop.
Do you wish to pause the processing of this function and continues?
点击是之后可以连上JTAG,可以在内存地址：0x11700000找到d800k008，cpu 可以reset ,也可以装入NANDWriter_DSP.out,但是一点go main
并不能到main(),而是直接运行，但是运行后也没有任何提示，这是为什么？

在IDE上的GEL菜单上点了相应的菜单项，结果如下：
   Memory Map Setup Complete.
   ---------------------------------------------
   PLL0 init done for Core:300MHz, EMIFA:100MHz
   Enabling Experimenter PSCs...
   Enabling Full EVM PSCs...
   PSC Enable Complete.
   ---------------------------------------------
之后cpu reset,再装入NANDWriter_DSP.out后点go main依旧直接运行，也一直没有提示。

总结下我的问题：如何通过JTAG调试加密版TMS320c6748BZWT E和烧写NAND FLASH程序？分解如下
1、非加密版的cfg文件可否有工具转换成加密版的ini文件，或者加密版是否也有跟非加密版AISgen for D800K008一样的GUI程序可以方便生成AIS bin文件
2、为什么我同一个.out文件非加密方式生成的bin文件用UART BOOT HOST可以正常引导，而加密版生成的bin文件用SECURE UART BOOT HOST却引导不了
3、key_hdr_sha256_enc.bin文件是如何生成的？是否可以不用或不需要自己生成？
4、通过UART引导解锁JTAG,连接时为何会出这样的提示，如何解决：
   The GEL callback "OnTargetConnect()" for the target "OMAPL138_TIXDS560/C6400PLUS_0" is still processing.
   The function could contain an inifinite loop.
   Do you wish to pause the processing of this function and continues?
5、连上JTAG后怎样能go main,然后一步一步运行，断电后不用UART引导解锁也能连上JTAG,并能调试。
6、连上JTAG烧写NAND FLASH，可否通过NANDWriter_DSP.out写入以前通过AISgen for D800K008生成的bin文件，写入以后能否正常引导运行，或是
   通过NANDWriter_DSP.out写入用SecureHexAIS_OMAP-L138生的bin文件后，ROM内的bootloader会自动解密bin文件然后加载到指定内存中吗？

你好！你所提到的这些问题也是我们现在面临的，现在解决了吗？能否分享下解决方法，我的邮箱hgw683@163.com，谢谢！

你好，我现在也在调试加密版的芯片，用你提供的这个文件确实可以解密调试，请问这个文件生成所需的 .ini 文件是怎样的？另外，.ini 文件中有个key_hdr_sha256_enc.bin，这个文件是怎么产生的？

0 Tony Tang 7 年多前回复 GC

TI__Guru 64206 points

key_hdr_sha256_enc.bin在这里只是为了测试，不需要这个文件。

你好，感谢你的解答！我现在可以解锁调试芯片。下一步要把程序烧写到NAND里，然后通过NAND启动，请问该怎么操作呢？使用GenericSecureUartHost.exe工具可以通过串口把程序烧写进NAND里面吗？

0 Tony Tang 7 年多前回复 GC

#1. 用通用的NANDwriter工程在解锁状态下把加密后的文件写进去就行了。

#2. 这里要注意个问题，用.ini配置加密后的文件的header里的CEK是明文，在更新用KEK加密CEK后的header到NAND时，不能只写header这几个word，要把整个1Kbyte都更新，否则会ECC出错的。

您好，请教一下，用KEK加密CEK时需要调用ROM里的函数，我该怎么调用呢？参考OMAPL138_C6748_Generic_Security_Users_Guide_v1.0.2.pdf文档中，在我自己的工程中添加了：sk_cwrap.asm 和 sk_cwrap.h。但是工程编译不通过，我该如何解决呢？谢谢！
