| 57 | Build U-Boot for qspi flash card | |
| 58 | ------------------------------------ | |
| 59 | ||
| 60 | .. code-block:: bash | |
| 61 | ||
| 62 | $ export CROSS_COMPILE=aarch64-poky-linux- | |
| 63 | $ make imx8mm_evk_fspi_defconfig | |
| 64 | $ make | |
| 65 | ||
| 66 | Currently, there is no direct support to write to QSPI Flash. | |
| 67 | Copy flash.bin to ${loadaddr} either from sd card or over network and then copy to | |
| 68 | qspi flash | |
| 69 | ||
| 70 | From sd card to memory | |
| 71 | ||
| 72 | .. code-block:: bash | |
| 73 | ||
| 74 | $mmc dev 1 | |
| 75 | $mmc read ${loadaddr} 0x00 <size_of_flash.bin/512> | |
| 76 | ||
| 77 | .. code-block:: bash | |
| 78 | ||
| 79 | $ sf probe | |
| 80 | $ sf erase 0 <size_of_flash.bin_in_hex> | |
| 81 | $ sf write $loadaddr 0x00 <size_of_flash.bin_in_hex> | |
