Posted on December 19, 2017 at 09:21Good morning,I'm working in my custom application based on STM32L4.Sometimes, a problem appears when trying to flash the device: If I try to flash it with Keil and Ulink2 interface, a message suddenly appears when...
Posted on November 24, 2017 at 15:08I have a simple project that toogle a LED. I try to add software protection to it.Basically, it does :main(){ Init_GPIO_for_LED(); LED_ON(); while(i++ < 10000000) {}; // yes, ugly LED_OFF(); while(1) {} //...
Posted on November 22, 2017 at 14:23Hello all,Our product is being programmed on test bench and after that it is locked setting the readout protection to level 2 (RDP level 2).My question is - is it normal for this process to take about 3 minutes?Ar...
Posted on October 02, 2017 at 17:36My current project involves some pretty complicated logic, required for firmware update over the air. So I ended up with solution, which contains bootloader and application code, compiled separately. My current mem...
Posted on August 07, 2017 at 13:57Hi forum,For my project, I use the STM32L0G6 MCU. My goal is to program the device, and then protect it against read-out, such that no copy of the firmware can be done.I also use the embedded bootloader ( see http:/...
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 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 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 ...
