AM2732 BootLoader时Appimage文件官方默认给的地址是0xA0000；这里有两个问题咨询下：

1、Appimage的地址能直接改吗，改了后对应的sbl_qspi.release.tiimage文件是否也需要修改对应的偏移地址？sbl_qspi.release.tiimage固件怎么重新编译（如需编译）？

2、AM2732 的Appimage有没有备份地址？即如果设定的地址（如0XA0000）无有效固件，BootLoader引导程序会去其他固定地址读取固件吗

Shine said:

Can the Appimage address be changed?

Yes App Image offset can be changed by the customer based on their use case.

Shine said:

If it can, does he need to modify the sbl_qspi.release.tiimage offset address?

No, the SBL offsets are fixed in the RBL boot flow. Please refer to the TRM for more information on ROM Boot Flow.

How to rebuild the sbl_qspi.release.tiimage if required?

Shine said:

Is there backup address for Appimage? That is, if there is no firmware in 0XA0000, will the bootloader search for the firmware from other address?

No, the redundant boot address is not supported in SBL. However the RBL supports redundant boot for SBL images at 0x0 and 0x40000.

Hope it helps.
