Posted on December 30, 2015 at 11:14 Hello, I've made a project based on stm32f103c8 mcu with keil4, init functions were generated in cubemx, The problem is MCU system clock: it is 8 MHz with any AHB Prescaler. System clock source = HSE, ...
Posted on December 15, 2015 at 20:08I've found a bug where the order of the interrupt handlers causes the HAL driver to get stuck in TxState==1, causing CDC_Transmit_FS() to always return USBD_BUSY leaving it unable to send any more IN transfers.The...

Posted on December 08, 2015 at 10:20Hi, I found another bug on USB library for the STM32F3XX (STM32_USB_Device_Library in STM32Cube_FW_F3_V1.3.0). STM32Cube_FW_F3_V1.3.0\Middlewares\ST\STM32_USB_Device_Library\Core\Src\usbd_core.c In the usbd_core.c...
Posted on December 01, 2015 at 08:41 While trying to use the HAL drivers to access the EEPROM section of the FLASH memory, I have come across a very weird issue When trying to program a zero(0) to an address, the HAL driver follows a spec...
Posted on November 21, 2015 at 16:01Hello everybodyI have found a BUG in STM32L4 hal lib (v1.1)I don't know if it is present in other STM32 family hal library.in stm32l4xx_hal_sd.c file at 1657 linepCardInfo->CardCapacity = ((pCardInfo->SD_csd.Devi...
Posted on November 05, 2015 at 18:00 Hello, I put together a new project using STM32CubeMx for the STM32L476 discovery board and generated some code for both Keil and IAR. Both had issues with the following lines: #define 3V3_...
Posted on October 30, 2015 at 15:55Hello, I use a Cortex M0 + to develop an application. With this cortex, I need to write in memory and this take 12 seconds by bytes. Could someone tell me if this is normal or not? thanks in advance . I'm using...
Posted on October 28, 2015 at 19:54 Hi, I'd like to say up-front that I'm one of those people thinking that the new CubeHAL is a great improvement compared to the old SPL. However, still there are things I don't understand. For examp...
Posted on October 21, 2015 at 12:44Hi, All, I downloaded STM32CUBEF4.zip from the official website. (STM32Cube_FW_F4_V1.9.0) I am exploring the driver dependency when I found the following problem. I am using STM32F411RE-Nucleo, by the way. Why in s...
