so i chang the MBED_CONF_TARGET_BOOT_STACK_SIZE in mbed_config.h ,but in didn’t help.I would like to know how can i solve the problem.

Hello,

probably first necessary information. In the mbed_config.h on lines 18-19

// Automatically generated configuration file.
// DO NOT EDIT, content will be overwritten.

Maybe here you will find some useful info
