Erase not working

[vg7190]

Hi,

I am working on nRF52832 board using Segger Embedded Studio for ARM 3.34a on windows 7 64 bit setup.

I am trying to erase page from RAM using "nrf_nvmc_page_erase()"  api but memory in that area is not getting cleared.

However I am able to overwrite using "nrf_nvmc_write_bytes()" ?

Can anyone help me out here by explaining why the memory is not getting reset to 0xFFFFFFFF when I erase it in segger.

Thanks in advance.

Hi,

Do you want to erase flash or RAM? The nrf_nvmc_page_erase() is used to erase a flash page (nonvolatile memory). To "erase" RAM, you could simply use memset(). Also, if you want to erase a flash page while using the SoftDevice (BLE stack), you need to use sd_flash_page_erase() instead, as the flash is protected by the SoftDevice.

Hi Einar,

Thanks for taking out time and helping me out. Actually It's flash memory which I want to erase.

and I am not using any softDevice in my application.

I see. In that case, nrf_nvmc_page_erase() which you use should have done the trick. Which address do you pass to it?
