Posted on February 16, 2018 at 10:38Hi all,I am trying to use the QuadSPI of STM32H743 as a classic SPI but using four lines. The point is that quadspi uses several phases (instrucction, direction, dummy, anternative, data) and I would like to skip...
Posted on February 12, 2018 at 13:42Hi,I am doing a project using STM32L432KC controller and EPCQ256 (32MegaBytes) -QSPI flash, Here I am able to Erase, Write and Read. but I am able to write only 1-4 MegaBytes and then writing is gets stopped (Here...
Posted on February 06, 2018 at 12:56Hello.I have a problem with QSPI. I try everything, but program doesn't work.I split my program to some parts.qspi_gpio_ini(); /* Init GPIO pins */ qspi_dma_init(); /* Init DMA */ qspi_init(); /* Init QSPI */ qspi...
Posted on February 09, 2018 at 12:28Hello.I have a problem. I have this function:/*instruction = 0x0B - Fast read * addr = address (0x00) - address * count = number of read data (4bytes) * dst = data out */void QSPI_fast_read (uint8_t instruction, u...
Posted on August 29, 2017 at 17:26Hi Guys,I'm struggeling with the I2S where the Datasource is an QSPI Flash (2 Datalines) on a STM32F446. How can I set on the right way the pointer to the Flash in the Function HAL_I2S_Transmit_DMA() for the DMA Tra...
Posted on August 22, 2017 at 04:23I'm experiencing strange behavior of QSPI peripheral (or may be flash chip itself -- N25Q128 in SO8; chips are not shiny new, but never used; datasheet Rev. 8 July 2014): despite what is stored in NVCR/VCR registers...
Posted on August 15, 2017 at 11:06Hello. I work with stm32f767ZI nucleo-144, and try use QUAD SPI bank1 to access W25Q128BV. All OK when i use 1 wire or 2 wire(dual mode), but when i use quad mode(4-wire), something went wrong. SPI Pins: ...
Posted on July 05, 2017 at 02:51Hi All,We are using an STM32F7 processor.We have a typical application that will store LCD images and other asset type data in qspi flash. The QSPI flash will be memory mapped. We also have external memory mapped RAM....
Posted on June 05, 2017 at 07:27Hi all!We're working on a board that uses the STM32F7 and we'd like to add external SRAM and NOR Flash. In both cases, we'd like to use Serial memory to save on IO pins, layout, etc.In looking at the schematics for th...
Posted on May 22, 2017 at 14:30We are investigating for a new STM32F7 based device with QSPI FLASH as a main memory to run the application from (XIP).We also need FLASH memory for mass storage, and what is not clear for us is if we can use the same ...
