I am using Atollic studio and the STM32F769 Discovery board.
I removed resistor R93 and fitted a 0R link to R92 so that the SWO line is connected to the ST-Link on the discovery board.
I have followed this tutorial to enable SWV and make use of ITM_SendChar:
I have enabled SWV and set the core clock frequency: currently 200MHz. (I verified this by calling SystemCoreClockUpdate() and checking the value of SystemCoreClock 200000000)
I have set the SWO clock to 2000kHz.
Unfortunately i do no receive any characters in the SWV console window within Atollic.
If i breakpoint the ITM_SendChar function i can see that its getting to the line "ITM->PORT[0U].u8 = (uint8_t)ch;" without issue.
I also just tried the "STM32 ST-Link Utility" with SWO viewer and can see a few characters when I press start but do not see a continuous stream of characters as i expect.
Anyone have a suggestion?
