Tool/software: Linux
Hi All,
When i am doing SD initialization sequence calls using IOCTL from my application,
For the CMD0, CMD8,CMD55,CMD41 i got responses, but for CMD2 i am getting time out error(error no:110)
IN [drivers/mmc/host/omap_hsmmc.c] : omap_hsmmc_do_irq()-> hsmmc_command_incomplete(host, -ETIMEDOUT, end_cmd); is hitting
When i print the interrupt status register: omap_hsmmc_dbg_report_irq: MMC IRQ 0x18000 : ERRI CTO is set.
CTO
Command Timeout Error
This bit is set automatically when no response is received
within 64 clock cycles from the end bit of the command.
For commands that reply within 5 clock cycles - the
timeout is still detected at 64 clock cycles.
Write 0x0: Status bit unchanged
Write 0x1: Status is cleared
Read 0x1: Time Out
Read 0x0: No error
Can any one help me, what need to take care, to overcome this.
am using micro SD card 128gb, SDR104
Thanks,
Anil
