RT1015 write a simple application execute from sdhost

[kensu]

Hi

I am testing an application. (SDK: evkmimxrt1015_iled_blinky)

I expect this application can execute from sdphost in download mode.

I think it's possible.

My Step are:

1. make RT1015 to download mode

2. Load my test application to 0x20208000

3. jump to 0x20208000.

The result is fail, the led is not blinking.

Can anyone teach me how to modify the evkmimxrt1015_iled_blinky so that it can run in sdphost jump?

Thanks

Ken

RT1015 is similar.

Hi Kerry

谢谢回覆

但我这边要试的是并不是SDPHOST + BLHOST将application烧到Flash内

我想试的是: 将application透过SDPHOST放在SRAM内，然后Jump直接执行这个Application

标准方式:

1. SDPHOST将FlashLoader.bin放到SRAM

2. SDPHOST Jump到SRAM的位置开始执行FlashLoader

3. BLHOST下command给SRAM的FlashLoader，将application烧录到Flash

4. DIP Switch改成boot mode执行application

而我想试的是

1. SDPHOST直接将Application.bin放到SRAM

2. SDPHOST Jump到SRAM的位置开始执行Application

有机会吗?

Hi kensu,

  感谢你的信息更新！

   你可以试想下flashloader.bin是什么？

   它其实就是一个特殊应用app对不对，然后是放到RAM，并且跳转过去运行的，所以如果你的app本身就是RAM的，我认为你完全可以这么干，你可以试试，如果有问题，我们再继续交流。

   你可以模仿flashloader那样去做。

Wish it helps you!
