nRF52832 flash erase problem:cannot erase the third page

[longycy]

Hi,

Now I test flashwrite example using nRF52832 with software version V12.2.0. I want to erase all memory pages with the code bellow:

for(pg_num=0;pg_num<=pg_total_num;pg_num++)
   {
       addr = (uint32_t *)(pg_size * pg_num);  //pg_size=4096 Bytes
       flash_page_erase(addr);
       
   }

But the erase fails when pg_num=3. I also have tested the other pages and all of them can be erased successfully except page 3.

What is the problem? Why I cannot erase page 3? Looking forward to your reply.

Thanks!

Best Regards Ye Chengyang

would you try these and pg_size is 1024 Words

#define PAGE_SIZE_WORDS 1024

// Retrieve the address of a page.
static uint32_t const * address_of_page(uint16_t page_num)
{
    return fs_config.p_start_addr + (page_num * PAGE_SIZE_WORDS);
}

void m_flash_erase_page_0(void)
{
	  erase_flag=1;
	  // Erase one page (page 0).
    fs_ret_t ret = fs_erase(&fs_config, address_of_page(0), 1, NULL);
    if( ret != FS_SUCCESS )
    {
        NRF_LOG_INFO("fs_erase error\r\n");
    }
		 while(erase_flag == 1) { power_manage(); }
}
