nuc970_sd: cannot mount SD card on tomato #66

Closed VS0x01 closed 3 years ago

VS0x01 commented 3 years ago

dmesg.log Used tomato defconfig, added CONFIG_NUC970_SD0_EN=y. Without this kernel boots.

Looks like the system ran out of memory while bring up the kernel. I'm cannot reproduce this issue with Tomato board's configuration plus CONFIG_NUC970_SD0_EN=y. Can you check /proc/meminfo for free memory space after system booting with Tomato board's config?

This system uses huge amount of memory during booting. Did you you build your own filesystem? or are using using the one came long with our BSP?

VS0x01 commented 3 years ago

The board came with 2013 uboot and 3.10.101 kernel and it mounted SD card. I built 2016 uboot and this kernel using buildroot. SD card has FAT filesystem. I just replaced uImage made with mkimage from uboot tools.

dmesg_3.10.101.log Here is the old log.

I still see lots of free space after system boot up. Did you made any change except load tomato board's config plus SD0 support? Was the SD card inserted during your test?

No.

Was the SD card inserted during your test?

Yes.

yachen commented 3 years ago

Can the system boot up if you removed the SD card?

VS0x01 commented 3 years ago

I write uBoot to SPI and it reads and boots uImage from SD card... I tried to boot kernel image via USB but it was hanging at Calibrating loop delay So Idk how to boot w/out SD card.

yachen commented 3 years ago

Hi, please try add lpj=744448 in bootargs in the dts file.

VS0x01 commented 3 years ago

Booted without SD card. The same error.

VS0x01 commented 3 years ago

I configured to compress rootfs and SD card driver works good, but there is still very little free memory.
