nrf52832 speed differences between custom board using this chip and development board using same chip (Fantsel BM832)https://devzone.nordicsemi.com/f/nordic-q-a/62730/nrf52832-speed-differences-between-custom-board-using-this-chip-and-development-board-using-same-chip-fantsel-bm832Hi. I am developing a custom application which interfaces with FStorage constantly. I have run into a peculiar situation in testing where the speed of writing to FStorage is 3.7x slower on our custom board, versus the development board.

Have you tried with an other board ?</p><div style="clear:both;"></div>RE: nrf52832 speed differences between custom board using this chip and development board using same chip (Fantsel BM832)https://devzone.nordicsemi.com/thread/255628?ContentTypeID=1Wed, 17 Jun 2020 20:41:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8f39d520-5a0a-4a07-b3e7-4de10bdc228cTurbo J<p>Just look into the PS (values from version 1.4):</p> <p>Time to write one word: min 67.5 max 338&micro;s. So one chip can be roughly 5x faster than the other. Page erase times are even worse!</p> <p></p> <p>But this many write cycles will destroy the flash memory in not time flat anyways (10.000 cycles specified) - back to the drawing board. I recommend using external SPI memory or upgrading to the NRF52840 with external QSPI memory.</p><div style="clear:both;"></div>
