Hello, I am doing a little bit of cross compiling but I have a problem with the linux interpreter. I am using the openstlinux-weston distro with the ld-linux-armhf.so.3 but the binaries after coming out of my cross compilation are using ld-linux.so.3...

Hello guys,I had recently a problem with executing LDREX instruction on the STM32H755 when MPU was activated for the specific memory region that covered the address accessed by the LDREX instruction. After executing LDREX instruction I got immediatel...

Hi guys, I have a problem with ADC conversion I would say. I put sine wave on ADC input and then I just transfer the value to DAC register, but the negative half of the sine wave is clipped. The code is just this ( Inside HAL_ADC_ConvCpltCallback):DA...

Hi guys,I would like to ask how properly place the function (code). I have solved the ld. script (have already the section in ram for code there) and functions which I want to place in ram has section attributes, but I read that the long call attribu...

Hi guys, I recently posted similar question but now I have some actual measurements.I have measured the frequency of the clock signal comming from st link to microcontroller which was 8 MHz (correct). Then I did setup of prescalers, configure system ...

Actually I got this info from ST directly, I created a support ticked, here is the answer from ST:We don't implement global monitor on STM32H7. We recommend to use the HW semaphore for synchronization.Best regards

Hi, this is the correct answer, I found it out already but I was too lazy to post it. :D

It really looks like a problem between MPU and exclusive address instructions, when the MPU is not active it works without any problems

I tried also specifically LDREXH instruction (still the same problem), the address accessed by instruction is aligned to the word, so that should not be a problem.
