[ERROR SPI Flash @20-07-19 20:23:04] Failed downloading firmware file to the board. In Keil, I got this: "No Cortex-m SW Device found".
Before according to this problem I download the Firmware in SPI flash which set the device in deep sleep mode immediately after system initialization. I saw that the downloaded firmware works. The device wakes up from sleep mode every 10 seconds and goes to sleep again.
My question is what can be the reason for image downloading failure and how can I fix this problem?
Thanks.
