Hi,we've been testing STOP2 modes and faced random core2 crashes.We use radio stack 1.15.0 LightCrash data at 0x20030000: 0x1170fd0f 0x00000000 0x00000939 0x2003fa20Any ideas?

We've switched to new DC-DC(LM3281) for main power supply and found that BLE TX stopped working correctly and not passing packet test anymore.After deeper investigation we found that our DC-DC in ECO mode has ripple/pulsation of 60mV/50uS, which caus...

Hi,we've been developing with stm32wb55 for some time and found that some combinations of STOP2 and radio usage causes permanent damage to RX path.It looks like that: device announce stops at some point and power consumption raises(+10mA). After rese...

Issue was caused by incorrect clocking scheme caused by clock configuration condition race on deep sleep enter/exit. Happens only if 64 MHz PLL used for system clock.Solution is kinda tricky: core1 is not allowed to perform switch to PLL, instead it ...

Any updates? This issues is severely affects our customers and we literally tried everything on our side. Most infuriating is that we can not restart core2 without restarting whole MCU.

Any updates? From our side we've switched to use HSI16 as SMPS clock in all modes as most examples show and still can reproduce it.

Awesome, waiting for results. Also can you link this to case 00178410 ?

Some device crashes every couple hours, other can work days. We don't have exact way to reproduce it.
