Hello @Nicolas_B
Let me thank you for bringing this issue to our attention.
An internal ticket was submitted to the dedicated team (Ticket Number: 225731).
I will let you know when the issue is solved.
As Workaround, I suggest that you add GPIO_InitStruct.Pull = LL_GPIO_PULL_UP under
static void MX_UART8_Init(void):
Thanks.
