工具与软件：
您好！
我们有一个带有 AM2432 ALV 芯片的定制电路板、我们选择的闪存是 IS25LP256D、并且处于 QSPI 模式。 现在、我们要在启动时将一些 Hello world 图像刷写到电路板中。
以下是我完成的步骤：
1.遵循 AM243x MCU+ SDK:添加对定制闪存设备的支持( TI.com ) ,获取 SDFM 参数并将其保存到.json 文件中。

----------------------------------------------------
2.修改 Flasher_JTAG_uniflash_AM243EVM 演示并获取.out 文件
3. 再次使用 JScript 初始化 SOC。
4.设置 Uniflash
5.加载映像并发生错误
有什么想法如何继续？
提前感谢您。
