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 currently trying to write to an external Flash via QSPI (SST26VF064B). So far I have been able to successfully configure the chip as required and I have also been able to read some configuration registers in the flash so I know I can communicate...
Hello,I recently created a custom board using the STM32F746. I'm encountering an issue with the QSPI interface. The problem arose when I replaced the external flash from the MT25QL128ABA model to the IS25LP128F model. I have checked the data sheet an...
Hi All,I have interfaced Winbond W25Q128 external flash and IS42S32400F-7TL external RAM to STM32H750IBK micro on my custom board. I have found an external loader file (stldr) for my pin configuration from a community member.I can program, read and ...
Hi All,Probably easy question, I would like to use DMA with QSPI (e.g. HAL_QSPI_Receive_DMA) but STM32CubeIDE/MX (1.16.0) is not giving me any options to configure it.There are no options, my parameter settings are belowQSPI is working fine in Indire...
Dear STM team,do you consider to add "Programmable IO" (PIO, as in RP2350) or FlexIO (as in NXP MCUs) to your chips?It would be really cool: often I need interfaces on MCU which are not available as a peripheral devices, such as: MDIO (Master), JTAG ...
Hi everyone.So I have W25Q80DV QSPI with STM32F412VET, I would like to use it to store some data. As per datasheet for W25Q80DV its flash is 8mbit and so I have the following initialization code : hqspi.Instance = QUADSPI;hqspi.Init.ClockPrescaler = ...
Hello, everyone. I am developing a prototype using a STM32L475 and the NOR flash memory MT25QL512ABB. I am using the QuadSPI peripheral for the communication with these parameters:I used the QSPI_ReadWrite_IT example as a reference to fill these para...
In the datasheet of W25N01GVZEIG,Data program load and quad data program load can transfer up to (2048+64) bytes.(The transfer of data between the controller and the external flash uses DMA)When I try to write 2048 bytes, nothing is written. The same...
I am trying to make an API for W25N01 flash. I have seen many post about this flash board and followed them. But they have not solved the problem of me not being able to read the data (so either my write function or read function is incorrect). The w...
