Up till now the CRC32 of received data was calculated unconditionally. The standard crc32 implementation causes long delay when large images were uploaded. The "dfu_hash_algo" environment variable gives the opportunity to disable on demand the hash (crc32) calculation. It can be done without the need to recompile the u-boot binary. By default the crc32 is calculated, which means that legacy behavior has been preserved. Tests results: 400 MiB ums.img file With crc32 calculation: 65 sec [avg 6.29 MB/s] Without crc32 calculation: 25 sec [avg 16.17 MB/s] Signed-off-by: Lukasz Majewski <l.majewski@samsung.com> Cc: Marek Vasut <marex@denx.de> |
