DFU extend code size after can not erase/write fstorage in application

[tuyenpham84]

Dear all,

I'd like to customize bootloader, I need more space so i modified flash address from example: FLASH ADDR (0x78000), SIZE (0x6000) to FLASH ADDR (0x69000), SIZE (0xA000). But when running application then it hang in erase flash function

uint8_t int_flash_page_erase(uint32_t start_addr, uint32_t total_page)
{
    nrf_fstorage_erase(&fstorage, start_addr, total_page, NULL);
    wait_for_flash_ready(&fstorage);
    return true;
}

I am using Segger embedded studio, Do i need change anything more?

thanks and regards,

Tuyen

Glad to hear that you figured it out. Please also check that the correct bootloader address is stored in either UICR or MBR (depending on what SDK version you use. which one is it?) If it is 15.0.0, then the bootloader address should be stored in UICR. If you use "nrfjprog --memrd 0x10001014 --n 4" to read this register.

BR,

Edvin
