I am currently trying to program this external memory using the external loader sub-project created when a project is created for the ST32H7R7. I have been able to successfully write the drivers for the external flash and I have also been able to por...
Hellowe're using MB1550 eval board with mb1379 daughter board and HDF5640-AF-V2.0 (OV5640 on a FPC) to test camera function. We'd like to tests another sensor, i'll design another FPC with our supplier but i need HDF5640-AF-V2.0 drawings to have the ...
I generated code using CubeMX that should permit me to transmit over SPI1 using DMA for RX and TX, as well as CPOL = 1 and CPHA = 1. I very slightly modified the auto generated CubeMX code but see nothing in the SPI CR1 or CR2 registers, nor the DMA2...
I'm using STM32H757I-EVAL and trying to implement SDMMC.However, I get some errors in these parts of code.At first, the error happened SDMMC_cmdAppCommnad.But now I can see the error SDMMC_CmdGoIdleStateI did change frequnecy of sdmmc, enable hardwa...
I am completely baffled by an issue I’m having with the STM32H7 using the SDMMC and a micro SD card. I have the F7 working and two H7 platforms that both have the same data timeout problem.The STM32F767ZI Nucleo board working OK with the SDMMC and a ...
Hi, I would like to test out the UART bootloader functionality for the demo board STM32F469I-DISCO. I am using reference documents AN2606 and Demo board schematic. I am assuming I need to follow below steps to achieve this.Please let me know if I am...
Posted on June 16, 2017 at 15:08I'm using NucleoF207G in that I'm trying to freertos queue using STM32Cube but i can't able to create any queue using xQueueCreate API . Pls give me a Proper suggestion .-ThanksK.Manikandan
In the QSPI chapter of G4series reference manual, we can confirm the support of external QSPI flash chip in mmap mode: "memory-mapped mode: the external flash memory is mapped to the device address space and is seen by the system as if it was an inte...
I am testing the functions of STM32U575 and found the following issue.I simply wrote this in main(): while(1){ for(i=0;i<160;i++); HAL_GPIO_TogglePin(GPIOC, GPIO_PIN_11); } where i is defined as uint32_t.HCLK is set to 160MHz by using PLLCLK with...
Hello All, I am progressing toward my goal. I am bit banging a GPIO port every 2 uS based on a Byte buffer. I can not use SPI because I need to send a predefine number of bit that is not 8 aligned. So I use a timer and every UIF event I reset the GPI...
