Riffbox emmc connecting error - GSM-Forum

I am facing an error when i try connecting my riffbox v1 with the rj45 isp emmc adapter.

With the USB Power connected it shows the following error:

Connecting to the SD/eMMC Card...ERROR
Set I/O Voltage reads as 2.80V, SD_CLK Frequency is 960 KHz

Connecting to the SD/eMMC Card Failed (ERR[0071], POS[0001])

Without the usb power the error code is:

Connecting to the SD/eMMC Card...ERROR
Set I/O Voltage reads as 2.80V, SD_CLK Frequency is 960 KHz

Connecting to the SD/eMMC Card Failed (ERR[0075]; POS[000B])

The error is happening with any phone that i try to connect with isp. The jtag interface works normally.

The jtag manager version is 1.89 and the box firmware is 1.54.

Thanks.

Hi,
If you have already tried Chip-off and it worked, try removing the clk resistor in isp.
