OS install error

[KYang.7]

I just got a stm32L475 Iot Kit.

And after compilation, I got this error .

st-flash 1.7.0-23-ga9adf9c

2021-05-21T22:17:24 INFO common.c: L4xx: 96 KiB SRAM, 1024 KiB flash in at least 2 KiB pages.

open(./BUILD/DISCO_L475VG_IOT01A/GCC_ARM/thingsboard-l475vg-iot01a.bin) == -1

2021-05-21T22:17:24 ERROR common.c: map_file() == -1

stlink_fwrite_flash() == -1

I don't know what this means.

Please tell me what I did wrong.

Thank you

Hi @KYang.7​ ,

• which example are you trying to compile?
• what are you using as compiler?

Hello,
Thank you for your answer of my question.
But never mind it, I already make it.
I compiled them on mbed online compiler on windows 10 and I copied a .bin file to my board.
It worked very goo.

Thank you anyway.
