TI中文支持网编译通过，下载底层程序时提示如下，我对照F28062地址分配，没有发现任何问题，不知道问题出在哪里：
C28xx: Loader: One or more sections of your program falls into a memory region that is not writable. These regions will not actually be written to the target. Check your linker configuration and/or memory map.
C28xx: File Loader: Verification failed: Values at address0x3D7BB4@Program do not match Please verify target memory and memory map.
C28xx: GEL: File: E:\DSP_bootmain\GDW300_FLASH_API\Debug\GDW300_FLASH_API.out: a data verification error occurred, file load failed.
1、使用串口在线升级， 0x3D7BB4地址看map映射
.cinit 0 003d7bb4 00000016 003d7bb4 0000000a rts2800_fpu32.lib : _lock.obj (.cinit)
003d7bbe 0000000a : exit.obj (.cinit)
003d7bc8 00000002 –HOLE– [fill = 0]
2、底层程序配置在OTP空间，cmd配置如下：
PAGE 0 : /* Program Memory */
/* Memory (RAM/FLASH/OTP) blocks can be moved to PAGE1 for data allocation */
RAMPRG : origin = 0x008000, length = 0x000300 /* 0x8000~0x82ff用于跑FlashAPI中的程序 */
BEGIN : origin = 0x3D7800, length = 0x000002 /* OTP boot的程序入口 */
OPT2FLASH : origin = 0x3D7802, length = 0x000003 /* 项目工程调用API函数的入口地址 */
OTP : origin = 0x3D7806, length = 0x0003F1 /* on-chip OTP */
OTPKEY : origin = 0x3D7BF7, length = 0x000001
OTPMOD : origin = 0x3D7BF8, length = 0x000001
// PRGFLAG1 : origin = 0x3E8000, length = 0x000002 /* Part of FLASHH，程序完整性标志 */
// FLASHBEGIN : origin = 0x3E8002, length = 0x000002 /* Flash程序入口. Used for "boot to OTP" bootloader mode. */
// FLASH : origin = 0x3E8004, length = 0x00FF7A /* on-chip FLASH */
// PRGFLAG2 : origin = 0x3F7F7E, length = 0x000002 /* Part of FLASHA，程序完整性标志 */
// CSM_RSVD : origin = 0x3F7F80, length = 0x000076 /* Part of FLASHA. Program with all 0x0000 when CSM is in use. */
// CSM_PWL_P0 : origin = 0x3F7FF8, length = 0x000008 /* Part of FLASHA. CSM password locations in FLASHA */
ROM : origin = 0x3FF27C, length = 0x000D44 /* Boot ROM */
RESET : origin = 0x3FFFC0, length = 0x000002 /* part of boot ROM */
VECTORS : origin = 0x3FFFC2, length = 0x00003E /* part of boot ROM */
map映射文件如下：
PAGE 0:
