Would you teach about SD2_CD_B and SD2_WP signal on i.MX6DL_SABRE-SDP?
According to a reference manual,(IMX6SDLRM.pdf)
The SD2_CD_B of i.MX6DL is assigned to GPIO_4(ALT6)(pin R6).
And, the SD2_WP is assigned to GPIO_2(ALT6)(pin T1).
However, In i.MX6DL_SABRE-SDP, the NANDF_D2(pin F16) is used as SD2_CD_B signal.
And, the NANDF_D3(pin D17) is used as SD2_WP signal.
(I understand that these signals are controlled by GPIO.)
Would you teach the reason for not using pins in which these signals were assigned?
Best Regards,
Solved! Go to Solution.
Both pins are set as a GPIO pin. So, it's also work if the GPIO_4 used as SD2_CD_B and GPIO_2 used as SD2_WP.
I think the arrangement of the PCB layout could be the reason for this different GPIO pins assignment.
