Hi Lukasz, I test with an extended timeout and no effect.
I already test multiples SD with very good quality SD Card with same problem (30-40 MB read / 10-20 MB write + SLC) ( just under the UHS-I SD cards ) The problem appears when FAT (or FAT entries) is inconsistent and despite a repair, the problem persists on writes of other futures files by the ubbot fatwrite command. Thanks for your help. ---- 2013/2/22 Lukasz Majewski <l.majew...@samsung.com> > Hi Jean, > > > Hi, > > > > I use the last uboot from your git and boot with it on AM3517 EVM > > from SD card > > without NAND. > > > > I use this option in uboot config : #define CONFIG_FAT_WRITE 1 > > > > I use intensively fatload / fatwrite commands at the boot before > > kernel loading. > > > > Sometimes, in about 2% of cases of boot, the FAT becomes inconsistent > > and I have > > systematically these messages at boot when I use fatwrite command : > > > > U-Boot 2013.01-gd3b9a66-dirty (Feb 21 2013 - 11:02:33) > > ... > > writing MODIFYME.001 > > mmc_send_cmd: timedout waiting on cmd inhibit to clear > > Those kind of errors are caused by exceeding timeout for receiving > response from your SD card. > > Could you try with other (different manufacturer) card? > > It seems like card/vendor specific - it depends on the firmware on the > SD card. > > Please look into a similar thread: > > http://article.gmane.org/gmane.comp.boot-loaders.u-boot/150636/match=rfc+mmc+fix+increase+timeout+value+sdhci_send_command > > > > mmc_send_cmd: timedout waiting on cmd inhibit to clear > > mmc_send_cmd: timedout waiting on cmd inhibit to clear > > mmc_send_cmd: timedout waiting on cmd inhibit to clear > > mmc_send_cmd: timedout waiting on cmd inhibit to clear > > mmc_send_cmd: timedout waiting on cmd inhibit to clear > > mmc_send_cmd: timedout waiting on cmd inhibit to clear > > mmc_send_cmd: timedout waiting on cmd inhibit to clear > > mmc_send_cmd: timedout waiting on cmd inhibit to clear > > mmc_send_cmd: timedout waiting on cmd inhibit to clear > > mmc_send_cmd: timedout waiting on cmd inhibit to clear > > 42428 bytes written > > ... > > > > > -- > Best regards, > > Lukasz Majewski > > Samsung R&D Poland (SRPOL) | Linux Platform Group >
