Hi,

After 2 months devoloping with simplicity studio, I find that I need to add RTOS or Miccrium as an OS to my Thunderbord BG22 to use pthread and mutex to manage tasks,

I add the os (RTOS for exemple) from project propriries -> C/C++ build -> project module, however when I compile the program I have the following errors in the make which I don't know how to solve :

Hi,

The screenshots are showing that the flash is being compared with the application and it is verified to be the same as the example.  The fact that the application does not seem to be running is indicating that the bootloader may have been erased from the device.  I recommend reading "UG266 Silicon Labs Gecko Bootloader User's Guide" and then create a bootloader project to use with the board.  But to get started quickly, from the Launcher perspective Demos section flash the SOC - Empty demo as this will also flash a bootloader back to the board.  Make sure the [Mode] is set to [Run] and not [Run and launch Energy Profiler].  After that you can flash your application to the board.  If you are using the Flash Programmer check the [Advanced Settings...] and make sure it is set to [Page Erase] so that the bootloader is not erased again.

Let me know if this helps or not.

Thank you,

jpitt

Hello everyone,

I'm using the Thunderboard BG22 and I'm working on a ble connection between a connected device (it will be my phone for sure) and the TB22.

I'm blocked in a task where I need to get the current time of the phone and send it back to the Thunderboard so I can analyse it  I don't know how to do that.

Hi,

I'm using the Thunderboard BG22, the problem that I have is sometimes I can't use the debgger of Simplicity Studio. whatI know is that the TB22 is not totally flashed as the console show:

Hi Adam,

Thanks for your remply,

I just tried the Polling example, I didn't change anything, like copy and past from the github link that you gived me, but it still doesn't work, I have everythime the same problem I can only read 2 characters,

I used 115200 for the bauderate as demanded for EFR32BG22, and I could see the 2 characters(no more than 2 characters) that I received in Putty's terminal.

best regards,

Nabil.

I just checked the USART_STATUS_RXDATAV  bit I don't understand why what I receive is 10('\n')

The USART_STATUS_RXDATAV  is already checked by the USART_RX fonction :

uint8_t USART_Rx(USART_TypeDef *usart)
{
	int i = 0;
    while ((!(usart->STATUS) & (USART_STATUS_RXDATAV)) && (i < 30)) {
	  i++;
  }
  return (uint8_t)usart->RXDATA;
}
