Hello. I have device with N32926U1DN cpu, which booting from SPI flash.
I want to boot from sd card. How can I make bootable SD?
Cant found any datasheets with boot description.
Here is starting log, SD booting has first priority:

我使用的是N32905，926应该也是类似的。在固件包中有一个SDLoader的工程。编译这个SDLoader 就是SD启动的文件。
将编译好的SDLoader.bin文件用TurboWriter工具写在SD卡的sector0中。然后就可以用SD卡启动了，会加载用户代码执行。
I have not 固件包中.
I saw only some documentation on nuvoton site, and i dont know where I can download flash packet.
