Hello,We noticed different behavior between J-Trace and I-Jet.We use both with IAR.It started on trying to trace code with stm32h743 eval board. we purchased j-trace for this issue, but it failed to trace code. Trying to do the same with I-Jet it suc...

Hello,Is there anyone who worked with TRACE ? I use j-trace with stm32h743 and IAR.On testing the trace with SEGGER cortex-m reference board (stm32h7407, which comes with the j-trace product) and IAR, the functionality works great.I then moved to stm...

Hi,With H7 the mapping is simple, we can use multiple streams at the same time, one channel per stream.But with L4 , it seems to be more complex, especially usage of "channel" terminology:For L4, Is it that we can use multiple channels ? Thanks,ranra...

Hello,I worked till now with H7 (stm32h743) and UARTs and had no issues at all.But recently I needed to port the project to L4 (stm32L496).For some reason UART now behaves differently:With polling there is no issue, but with interrupt or dma:As long ...

Hello,Is it that application can only run from ITCM ? When I try to run from other SRAM such as SRAM1, it get into MEM IRQ handler.Another issue is that on running from ITCM the HAL_Delay is much faster compared with running from internal flash (Xip...

Hi,One more note,Seems that with I-jest it works( while with j-link it doesn't !)j-link prints on start debug: https://pastebin.com/4xcGWKLxI-jet prints on start debug: https://pastebin.com/SjY7i2mhAny idea why these debuggers behave different ?Thank...

Hello,Did anyone managed to trace stm32 ? We want to use IAR with j-trace, and we get trouble with it.Yet using Segger's demo for stm343 it work (https://wiki.segger.com/STM32H7#Tracing_on_ST_STM32H743)It seems that demo uses pex file which is a MUST...

Hello,Is it that this solution is only for L4 ? or can it be used with F4 too ?Another thing, I find in code USART_CR1_FIFOEN. Can't it be used for solving the same problem ?Thanks!

Thanks, but for L4, cis it correct to say that multiple channels can be used at the same time ?

Hi,Yes, I use bootloader, which copies it to RAM and jump to start address.The bootloader already works perfectly if it jumps to flash and run from flash.The questions were raised about sram - which are theoretical question , to understand if what we...
