Mbed OS Bugs
1

Hello,
I tried to upgrade to mbed os 6.5 with my DISCO-F429ZI_Board.
I obtained this error :
L6218E: Undefined symbol wait_ms (referred from BUILD/DISCO_F429ZI/ARMC6/BSP_DISCO_F429ZI/Drivers/BSP/STM32F429I-Discovery/stm32f429i_discovery.o).
Could you help me ?
Thanks for advance
Didier

wait_ms is deprecated and has been removed from Mbed OS6, you should use ThisThread::sleep_for() now.

Hello,

if any library contains the wait() or wait_ms() functions, then yes, you must to replace it.

  • old wait(1) to new thread_sleep_for(1000) or ThisThread::sleep_for(1000)
  • old wait_ms(1) to new thread_sleep_for(1) or ThisThread::sleep_for(1)

The thread_sleep_for() function will also work with the Bare metal profile without further settings.
