From mboxrd@z Thu Jan 1 00:00:00 1970 From: Lukasz Majewski Date: Fri, 28 Aug 2015 15:50:20 +0200 Subject: [U-Boot] [PATCH 1/2] mmc: dw_mmc: Increase timeout to 20 seconds Message-ID: <1440769821-24005-1-git-send-email-l.majewski@samsung.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de The commit: d9dbb97be0e4a550457aec5f11afefb446169c90 "mmc: dw_mmc: Zap endless timeout" removed endless loop waiting for end of dw mmc transfer. For some workloads - dfu test @ Odroid XU3 (sending 8MiB file) - and SD cards (e.g. MicroSD Kingston 4GiB, Adata 4GiB) the default timeout is to short. The new value - 20 seconds - takes into account the situation when SD card triggers internal clean up. Such process may take more than 10 seconds on some cards.
