Posted on August 04, 2017 at 11:48Hi,I have a legacy device, a bootloader, running on a STM32F101CBT6.I don't have it's code, so I'm not sure of what's it doing exactly... but I know it locks the flash.My goal is to upload an application, with a pay...
Posted on July 13, 2017 at 18:04Hi all,I am using the STM32L011G3U6 with 8kB FLASH.We deliver this chip programmed with a firmware that is read protected (RDPROT = Level 1)Our customer should be able to write certain data in predefined non-volatile ...
Posted on June 27, 2017 at 18:17Hi St communityWe have a custom board based on STM32F429 that runs a gateway application between a wireless transciever and an ethernet link.To check for frames integrity we use a CRC16-CCITT algorithm, each bytes req...
Posted on June 23, 2017 at 04:01Hi everyone!I'm using STM32F105 MCU , and I'd like to explore built-in DFU featureWhen I set BOOT0/BOOT1 pins per datasheet and reboot the MCU, the feature always works ok no matter how read out protection is set in o...
Posted on June 21, 2017 at 10:14I tried to enable the read out protection on a stm32w108 using stm32 stlink utility. The problem is that the process fails, and I end up having three locked full erased chips. The option byte reports that rdp is enabl...
Posted on June 16, 2017 at 12:10Hi,The ProblemI am running uCLinux on the STM32F746. I am using a gadgetfs-based mass storage device with the SD card for a backing file. The USB PHY is an external SMSC ULPI chip. This works fine when connected to mo...
Posted on July 02, 2015 at 17:53Hello all,I am new to this forum but it has so far been a very good resource for me to learn how to work with the STM32F4 MCU.I have managed to enable RDP Level 1 using software but I was wondering if there was a way ...

Posted on April 28, 2017 at 10:40I have two STM32F103 connected together with SPI in full duplex mode. They changing 700 halword with DMA and CRC enabled. The communication is fine (no crc or other error) but there is this line of code in the SPI_DM...
Posted on April 22, 2016 at 12:31Hi,I need to implement an existing circa algorithm [1]. I have a table driven C implementation, but I would like to use the STM32L4 CRC peripheral. I�ve read the chapter in the reference manual, and I know which para...
