Hi
Please read the chapter 2.1. Bootloader workflow overview of AN12218:
The second step is to initialize the timeout mechanism. After a reset, the microcontroller will poll the selected communication channel, if no activity was detected during the time allowed by the timeout mechanism the device will attempt to execute the last application loaded, if the device hasn’t received an application it will get stuck in a loop. In order to attempt the download of an application another reset is required.
The timeout value is configurable and it is set by default to five seconds. Only one second multiples can be selected, in order to change the timeout value simply set the desired value in ‘sources/drivers/inc/timeout.h’ line 14.
/* Define timeout value, the base is 1s */
#define TIMEOUT_VAL 5
It seems that you clicked Download on JAVA Serial Bootloader Interface after the timeout. It is recommended that you click Download before the timeout or increase the timeout value.
Best Regards,
Robin
