Mass Storage Device (MSD) Update for SLN-VIZN-IOT

[gto02880288]

你們的手冊上寫著按住 SW1 鍵直到閃紅、藍、紫燈就可以進入MSD mode，不過我按了很久都沒辦法進MSD mode，是不是產品的缺陷?

Hi,

Are you holding SW1 during boot? As you mentioned it should enter MSD mode by doing this. Could you please explain what is the behavior you are seeing on your side?

Best regards,

Felipe

Hi,

I have been experiencing the same issue with my board. At first I could detect it as MSD when long press SW1. Then I tried to flash boot loader and bootstrap program to hyperflash. (These are sample codes given with SLN-VIZN-IOT SDK). After that I can't enter MSD mode using SW1. Hardware is still working, because there is no problem in running other programs both in RAM and hyperflash. Could you please give an immediate assistance.

(I am using SLN-VIZNAS-IOT board, MCUXpresso IDE and sdk_2.x_SLN-VIZN-IOT version 2.5)

Thank you

Your manual says that just hold SW1 key to enter MSD mode, But I still couldn't enter MSD mode. I want to know if it's your product's problem?
