nRF52832 Flash as EEPROM with ESB.

KeyWords: nRF52832  ESB  Flash as EEPROM  SDK:17.0.0

Hello, I an using nRF52832 developing ESB communicution with other nordic product.

I need to save some infomation, so used flash as eeprom, used the last page of flash: page_127 ：

#define USER_CFG_ADDR_ST (127 * 4 * 1024)
#define USER_CFG_ADDR_SP (128 * 4 * 1024)

I used the following functions:

nrf_fstorage_init(&my_fs, p_fs_api, NULL);
    nrf_fstorage_erase(&my_fs, USER_CFG_ADDR_ST, 1, NULL);
            erase(nrf_fstorage_t const * p_fs, uint32_t page_addr, uint32_t len, void * p_param)
                queue_start();
                    queue_start();
                        queue_process();
                            rc = erase_execute(m_p_cur_op);

when the code run here （i debuged with log msg），can't continue run any more.

I don't know what's wrong, can any one tell me what should i do.

Hi

Are you using a Development Kit or a custom board and an external debugger? A few things you can try:

First, set NRF_FPRINTF_FLAG_AUTOMATIC_CR_ON_LF_ENABLED to 0 in sdk_config.h and see if you can read any debug messages now.

If you're using a Development Kit, you can try using the UART backend for debugging instead, to see if you can see any more messages if you try writing the log information to a terminal like PUTTY or Termite. To do this, set NRF_LOG_BACKEND_RTT_ENABLED to 0 and NRF_LOG_BACKEND_UART_ENABLED to 1 in sdk_config.h

Best regards,

Simon

Thanks for your replay!

I did as you suggested, but nothing help. So i decide to use an EEPROM IC for my function.

If you have other idea, please let me know as soon as possible.

thanks again!

Hi Simonr! 

Good news! My problem solved.

The API should be "nrf_fstorage_nvmc" not "nrf_fstorage_sd".

But I have used "nrf_fstorage_sd" in BLE development on the same board.

I still confused why the same API has different effect, can you please tell me.
