https://devzone.nordicsemi.com/f/nordic-q-a/81030/how-to-add-theother-qspi-flash-gd25q64eI use the nRF5_SDK_15.2.0_9412b96 , the sample is use a QSPI FLASH(MX25R64), and we want to change this QSPI FLASH. we will use GD25Q64E, which code should be modify?en-USTelligent Community 13Mon, 25 Oct 2021 12:55:50 GMThttps://devzone.nordicsemi.com/thread/335750?ContentTypeID=1Mon, 25 Oct 2021 12:55:50 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d5612c4c-ae29-479c-babf-a3d15a4d50adSimonr<p>Hi</p> <p>You need to compare the datasheet of the&nbsp;<strong>GD25Q64E</strong>&nbsp;and the<strong> <a href="https://www.macronix.com/Lists/Datasheet/Attachments/7913/MX25R6435F,%20Wide%20Range,%2064Mb,%20v1.5.pdf">MX25R64</a>&nbsp;</strong>and find out what the specific differences are. Some of the OP codes seem to be similar, which is helpful, but you still need to modify the flash parameters that differ in thenrf_serial_flash_params_t struct in&nbsp;<strong>nrf_serial_flash_params.c.&nbsp;</strong>You might also need to change the blk_id and blk_size to fit the GD flash device if the block indez/size differ from the MX25R64.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
