I running my zephyr based firmware. Before it is run a boot loader selects the firmware image. This bootloader sets the FLASH_OPTCR register. All sectors are disabled for writing(erasing). using flash_write_protection_set function doesn'...
Describe the bug I am facing a similary problem with my disco_l475_iot1 board which has stm32l475 MCU. I am using mcuboot for updatehub app. I am not able to erase flash memory partition. A clear and concise description of what the bug i...
Hi, I had an earlier thread: [SOLVED] JFlash overwrites incorrect pages where Segger provided a solution using GDB to prevent the J-Link erasing data in the flash that we need to protect. I have the same problem with J-Flash: we use a 2-step programming
Problem: sector erase does not work I am a newbie to QSPI flash, jumping from example to example. I still have not understood whether to send 1 or 2 CMD bytes for the erase LUT sequence:- the Micron datasheet suggests there is noe CD byte, and 4 address bytes, and that's it...
I am using MIMXrt1020 evk .I want to erase sector number 593. But whenever I enter in this instruction flexspi_nor_flash_erase_sector(EXAMPLE_FLEXSPI, 593 * SECTOR_SIZE); my controller goes into fault. Please suggest me the solution Tags: flexspi mimxrt1021 nor erase...
