Resolved! Quad SPI Single Mode Read Chip ID from Riverdi

Hello,I'm using a Nucleo-WB55RE board with Quad SPI in single mode. I'm trying to start very simply by just reading the chip id from a Riverdi BT81X display. I have captured two waveforms, one via a Nucleo-446 board using regular SPI and one from t...

Resolved! STM32WB + QSPI for nand flash

My development environment is stm32cubeMX and IAR.First of all, the configuration I programmed is like this.1. Init (write Status Register WP-E set 1)2. Block Erase (to the address where i will store the data)3. Write data to buffer4. Program Execu...

Resolved! Is DMA able to access external FLASH in memory mapped mode?

I am fiddling with a STM32WB5M discovery kit.This kit includes a QuadSPI external NOR FLASH chip and i need to understand this in order to make early design choices. Could the DMA access that external FLASH memory space?I didnt try it yet, but my lim...

STM32WB55: Maximal execution time running the code on QUADSPI

Hi thereHow to calculate the maximal possible CPU execution time for the STM32WB55 when running fetching the code from external flash?Kind Regrads

Resolved! How to use external QSPI flash to save sensor data

Hello,I am currently using STM32WB55 with QSPI external flash.Currently, the plan is to use it without Bluetooth, for now.I am able to write and read the flash in the program.The plan:Record for 24 hours with DMA from sensors to flash.Upload another ...

Resolved! QSPI clock pausing before sending each byte when transmitting during data phase

Hello,I am using the STM32WB55 nucleo development kit to communicate over QSPI with an external memory device. I presently have the QSPI interface configured for DMA operation, and I am able to use the external device successfully. However, when tran...

Resolved! STM32WBXX QSPI: Missing Parameters I would like to know why the HALF CYCLE DELAY parameters related to HAL_QSPI is deleted for this MCU?

Resolved! STM32WB5MMG: Not included in QuadSPI Applicable Products?

Reference: https://www.st.com/resource/en/application_note/an4760-quadspi-interface-on-stm32-microcontrollers-and-microprocessors--stmicroelectronics.pdfIs there a particular reason (technical or HAL-driver related) that is behind this non-inclusion ...

Resolved! STM32WB55 QSPI and DMA

I have a custom board with a quadSPI chip installed. I can program a 256-byte page just fine using HAL_QSPI_Transmit(), which I'm monitoring with a logic analyzer. But when I try to do this with HAL_QSPI_Transmit_DMA(), nothing happens on the line...

Resolved! 1.8V GPIO on STM32WB55 Nucleo Pack

Is there a way to use 1.8V NAND Memory Chip using Quad SPI GPIOs in STM32WB55 Nucleo Pack? I already wired-up the 1.8V NAND chip and connected to Quad SPI pins of the Nucleo Pack, but I haven't powered this board up yet.
