工具与软件：
您好、TI 专家！
我正在尝试修改 SBL、以将固件(XIP 格式)写入闪存。
SDK 版本为 MCU+ SDK v10.00.00.20。
我在这里有两个问题、如果你能回答、我将不胜感激。
我无法在 SBL 过程中写入闪存。 (Flash_WRITE()的返回值为错误。)
我采取的步骤如下。
1.我从 SBL 示例中删除了固件读取过程[*1]并添加了闪存写入过程。
2.我参考了 OSPI 示例[*2]的闪存写入过程。
*1: examples/drivers/boot/sbl_ospi.
*2: examples/ospi/ospi_flash_io
生成的源代码(main.c)如下所示。
闪存写入过程从第135行开始。

已确认仅运行 OSPI 示例[*2]时、闪存写入过程可以正常工作。
SBL 中错误的原因未知、因此如果您有任何线索、请告诉我。
我想使用引导加载程序模块在每个内核上执行 XIP 操作、
但是、在将 XIP 格式写入闪存时、我应该将.appimage_xip 写入什么地址？
我是否应该将其覆盖到与.appimage 相同的地址？
请告诉我步骤。
此致、
武田太郎
