关于 280023 CMD配置问题

  在调试时，程序烧录在flash中，  28002x_generic_flash_lnk.cmd配置如下时程序能正确烧写运行

改为如下时程序编译通过，但烧写一半出错,不知是何原因?

"改为如下时程序编译通过，但烧写一半出错,不知是何原因?"

请问您具体修改是什么？另外具体的出错信息是什么？请您详细说明一下

,

jie gong：

只是把FLASH段分开了，1整段和16段的区别，（FLASHBANK1 共一段， FLASH_BANK0_SEC0– SEC15 共16段），按上面的配置，就有两种完全不同的结果

,

Susan Yang：

这个问题建议您先看一下

software-dl.ti.com/…/c2000_c28x-compiler-understanding-linking.html

不知具体是什么报错？有可能是部分section不够，需要合并section

,

jie gong：

还有个问题，程序 我是从28034上移植到280023上，现在但FLASHBANK1超过50%时程序编译通过，烧写程序时擦除FLASH后，烧写进度走了一段后就报错 Load program Error。只要将代码减少到FLASHBANK1小于50%时，烧写都正常，程序也能跑。

,

Susan Yang：

请问具体详细报错信息是什么？关于移植您可以参考

jie gong：

当FLASH空间超过50%时烧写出错是不是280023的FLASH空间只有32K，28034的FLASH空间有64K，我用的CMD文件是C2000 WARE SDK 中的28002x_generic_flash_lnk.cmd。

28002x_generic_flash_lnk.cmd 中FLASH空间如下

/* Flash sectors */ /* BANK 0 */ FLASH_BANK0_SEC0 : origin = 0x080002, length = 0x000FFE /* on-chip Flash */ FLASH_BANK0_SEC1 : origin = 0x081000, length = 0x001000 /* on-chip Flash */ FLASH_BANK0_SEC2 : origin = 0x082000, length = 0x001000 /* on-chip Flash */ FLASH_BANK0_SEC3 : origin = 0x083000, length = 0x001000 /* on-chip Flash */ FLASH_BANK0_SEC4 : origin = 0x084000, length = 0x001000 /* on-chip Flash */ FLASH_BANK0_SEC5 : origin = 0x085000, length = 0x001000 /* on-chip Flash */ FLASH_BANK0_SEC6 : origin = 0x086000, length = 0x001000 /* on-chip Flash */ FLASH_BANK0_SEC7 : origin = 0x087000, length = 0x001000 /* on-chip Flash */ FLASH_BANK0_SEC8 : origin = 0x088000, length = 0x001000 /* on-chip Flash */ FLASH_BANK0_SEC9 : origin = 0x089000, length = 0x001000 /* on-chip Flash */ FLASH_BANK0_SEC10 : origin = 0x08A000, length = 0x001000 /* on-chip Flash */ FLASH_BANK0_SEC11 : origin = 0x08B000, length = 0x001000 /* on-chip Flash */ FLASH_BANK0_SEC12 : origin = 0x08C000, length = 0x001000 /* on-chip Flash */ FLASH_BANK0_SEC13 : origin = 0x08D000, length = 0x001000 /* on-chip Flash */ FLASH_BANK0_SEC14 : origin = 0x08E000, length = 0x001000 /* on-chip Flash */ FLASH_BANK0_SEC15 : origin = 0x08F000, length = 0x000FF0 /* on-chip Flash */

,

Susan Yang：

谢谢您的详细信息。看起来是flash大小差异引起的这样的问题。目前您map文件中显示flash使用量是多少？

,

jie gong：

对比280023 与 28034 IQmath有区别

在280023 CMD 文件中是否要添加以下代码（/* 此处IQmath */） ，

FLASHBANK1 : origin = 0x00080002, length = 0x00007FF0 FLASH_BANK1_RSVD : origin = 0x0008FFF2, length = 0x0000000D /* Reserve and do not use for code as per the errata advisory "Memory: Prefetching Beyond Valid Memory" */

IQTABLES : origin = 0x3F1402, length = 0x00166D    /* 此处IQmath */

BOOTROM : origin = 0x003F0000, length = 0x00001400 BOOTROM1 : origin = 0x003F2A6F, length = 0x00005000 BOOTROM_EXT : origin = 0x003F8000, length = 0x00007FC0 RESET : origin = 0x003FFFC0, length = 0x00000002

IQmath : > FLASHBANK1    /* 此处IQmath */ IQmathTables : > IQTABLES , TYPE = NOLOAD   /* 此处IQmath */ IQmathTablesRam : > RAMLS4567   /* 此处IQmath */

不知是否正确？请指教！

,

jie gong：

解决了，IQmath的设置问题，IQmathTablesRam 这个段要用在FlASH中，IQmath手册上有说。感谢支持！！！

,

Susan Yang：

很高兴您能解决问题，谢谢您的详细反馈！
