I added the following debug line:
--- a/drivers/mmc/fsl_esdhc_imx.c +++ b/drivers/mmc/fsl_esdhc_imx.c @@ -499,6 +499,7 @@ static int esdhc_send_cmd_common(struct fsl_esdhc_priv *priv, struct mmc *mmc, irqstat = esdhc_read32(®s->irqstat);
if (irqstat & CMD_ERR) { + printf("****** -ECOMM comming from 1\n"); err = -ECOMM; goto out; }
And this is what I got after issuing a 'reboot' command in Linux:
# reboot # Stopping network: OK Saving random seed: [ 5.255229] random: dd: uninitialized urandom read (512 bytes read) OK Stopping klogd: OK Stopping syslogd: OK umount: devtmpfs busy - remounted read-only [ 5.309631] EXT4-fs (mmcblk1p2): re-mounted.

Any ideas as to why CMD_ERR bit is being set in the irqstat register?
Thanks
