I'm a maintainer of TinyUSB project, to ensure the code quality we have some strict GCC flags enabled. Wcast-align and Wcast-qual cause SEGGER_RTT.c failed to compile with following error: Source Code (11 lines) Please either fix them or suppress the error by adding: Source Code (4 lines)

Hi, I tried the new J-Scope V7.52a, I still have some issues: 1. J-Scope crashs trying to add new symbol with the "+" button. 2. With RTT selected, start button is not clickable, it's not usable at all. 3. In ELF selection dialog, file extension is restricted to .elf, but IAR use .out as default extension, it's not very practical.

Hi, I'm using J-Link V7.50 with LPCXpresso4367 board. I've tried both 5.10 and 6.11, both of them crashes on clicking the "..." button for device selection. Is J-Scope deprecated ?

Hi, I've attached a demo project.

Hi, I've imported an IAR project, with no configuration modification, while linking I got 'Relocation R_ARM_ABS32 to weak symbol '****' is invalid' error. segger-as: version 2.10 segger-cc: version 10.6.2 segger-ld: version 3.04 The functions are defined as weak : __attribute__ ((weak)) void tud_cdc_rx_cb(uint8_t itf) No matter the weak function is implemented or not, this error is generated.

Hello, I know STM32G0 can be unlocked when launching a debug session, but is there any command to unlock it explicitly ? I can't find it in STM32 Unlock tool, nor with the command unlock <DeviceName>.

Hi, As you can see the memory viewer of Embedded Studio, it failed to access memory at address 0x0. This is not an intended behavior, as the Flash content of 0x08000000 (or system memory, depend on boot0 pin) is mapped at address 0x0 at boot time (refer to RM0444, section 2.5 Boot configuration, page 58). So this is definitely not a IAR issue. forum.segger.com/index.php/Att…5fa92d398c9f128e0fc0fcf5e Best regards,

I found the corrupt of the NMI interrupt, it's cause by SRAM parity check I enabled previously in another project. Since by default RAM is not erased at startup, parity error could occur. So I reset option bytes. Following are 2 memery map at address 0 using ST-Link+IAR & J-Link+Embedded Studio. forum.segger.com/index.php/Att…5fa92d398c9f128e0fc0fcf5e forum.segger.com/index.php/Att…5fa92d398c9f128e0fc0fcf5e

In the attachment there are: - iar fail.log : J-Link log of the failing session with IAR, we can see the MemMap error message. - ozone.log : Same error when debugging iar output file with OZone. - test.zip : Iar output file. - embedded studio.zip : embedded studio log. No MemMap error, but as soon as I click run MCU enters NMI. Both STM32G071CBT6 minimal system board (no peripherals, only 10uF + 100nF decouple capacitors) and NUCLEO-G071RB(on board ST-Link disabled by jumper) are tested.

I've reached IAR support, using their demo project same error occurred. Seems like not an issue of IAR ?

Thanks for your reply. In fact I link my application to 0x08000000, same error occurred with sample code shipped with STM32Cube. Here is my linker script: Source Code (33 lines)Another bug is as soon as RTT client is opened, MCU goes into NMI interrupt. I'm also going to ask technical support of IAR, since maybe they did something wrong.

Hi, This error occurred I click debug, but debug function actually works. Probe: J-Link V10 EDU 6.40b IDE: IAR 8.32 MCU: STM32G071CBT6 forum.segger.com/index.php/Att…5fa92d398c9f128e0fc0fcf5e Do you need more error log ?

Sorry, it's just a program 1st time initialisation issue

Hi, Using J-link v6.20g with MKM34Z256, primask is not cleared after the execution of a script. Strangely I even tried add __enable_irq() in my code, but primask is always 1. :( Source Code (18 lines)

I have a task running at 1Hz and several IRQs running at higher speed. In the context window I was shocked that the frequency of this task is about 5/6 Hz and run count is added by 5 or 6 every second, then I found out that's because the execution of this task is interrupted 5 or 6 times by IRQs, as they are displayed in the timeline. I feel these two information is very misleading, as in most case what we care is the real run count/ frequency of a task, and how many time a task is interrupted b…

Hi, For ISRs, we can use SEGGER_SYSVIEW_RecordEnterISR() combine with SEGGER_SYSVIEW_SendSysDesc("I#15=xxxxxxx"); to trace them easily. But for function calls, in order to display them correctly, we need to write a description file, which is not always practical. So what I done is hacked the ISR record function: Source Code (1 line) I know it's not a good idea to modify sources files of SystemView directly, could you provide a easy way to record function call like this ?

Hi, Using the 6.14c software, I noticed that when I click debug in the IAR, the virtual com port already opened not work anymore. In order to let it work, I must choose another baudrate. Step to produce the issue: 1. Make a loopback connection on VCP and connect SWD to the MCU 2. Use Tera Term to test the vcp port, it should work. 3. Click download and debug in IAR 4. VCP port not work anymore even if I close and relaunch Tera Term 5. Change the baud rate in Tera Term and VCP works until next de…

Hello, I'm evaluating emFile with STM32F4 and IAR compiler. In my project I'm using USB to mount nand flash and display new files after USB is ejected. However, I found FS_GetVolumeFreeSpace() didn't give me the newest free space after some files are created or deleted, in my case there are only two ways to get the actual free space: 1.Reset the MCU, so the file system is also reinitialized. 2.Format the flash, it gives the correct space. Anyway to solve this? Thanks,
