Data in the RAM of STM32
I use IAR to program STM32，the map file shows that ：the RAM is divided to 1.data Section；2.CSTACK and HEAP section；3.bss section；4.Unassigned part of the RAM。What I want to know is that:The Unassigned part of the RAM is used to do what? Because I w...
Resolved! TIM DMA Burst works in incorrect sequence,
I use tim dma burst to update CCRx(x=1\2\3\4),my code works,but the CCRx value not assigned in correct sequence. My purpose is to let CCR1= 360�?CCR2= 720�?CCR3=1080.But the result are random.TIM and DMA config codesvoid tim_config(){ uint32_t addres...
Resolved! What is the name of the Timer 6 count register? TIM6_CNT is what the documentation says but that is an unknown variable to the compiler.
I need a blocking very short time delay.So I set up Timer 6 to run at 90 MHz, with no interrupts.I need delays from 0.5 to 30 microseconds for an interface I have to bit-bang.I was hoping for a simple delay routine like this:void Timer6_delay(uint16_...
Can I load & run my 192kb program into multiple smaller FLASH sectors?
Can I load my 192kb program file into multiple smaller FLASH sectors (i.e. Sector 1 (32kb) + Sector 2 (32k) + Sector 3 (32k) + Sector 4 (128k). Can it run from these smaller segments?Guidance appreciated....
STM32CubeProgrammer UART Verification Fails on STM32H7
Hello,I am using stm32cubeprogrammer 2.7.0 for Mac ( I am on Big Sir)When programming a STM32H7 using UART I get the following error: I don't seem to get the error on my stm32f4. Any Ideas/Fixes that would enable this to work? I am embedding the CLI ...
Resolved! Screwing Nucleo F767ZI
Hello community ! I hope you are doing well,I have actually a question which is kind of "DIY" and is not MCU developpment related. I have Nucleo F767ZI, and I need to get it screwed to a plexiglas board. I didn't find out whether the holes next to ar...
Resolved! STM32F437IIH6 ECC and NAND Flash size
Hello.1. Whether the hardware ECC for STM32F437IIH6 support error detection and error correction? STM32F437 is connect to NAND Flash through FMC with Bank2. Reference manual RM0090 section 37.6.6 describe it can perform 1-bit error correction and 2-b...

Resolved! Please, where can I find a "key_pair_generation" example code for the Discovery Kit B-L4S5_IOT01A? (STSAFE)
I tried porting the example code has been done for the Nucleo board to the B-L4S5_IOT01A but I get STSAFEA_COMMUNICATION_ERROR as result. SEE BELOWKey pair generation demonstration: 1. Generate key pair through STSAFE-A's private key slot 1 => Use ...
