IOMux.exe & iMX53RM.pdf conflict

[kamejoko80]

Hi all,

There are some points of difference between the IOMux (v2.0.27) tool and the iMX53RM.pdf (Rev. 2.1, 6/2012). In the iMX53RM, the Table 7-25 said that:

Table 7-25. SPI IOMUX Pin Configuration

Signal  ECSPI-1

MISO   EIM_D17.alt4

MOSI   EIM_D18.alt4

RDY     N/A1

SCLK   EIM_D16.alt4

SS0     EIM_EB2.alt4

SS1     EIM_D19.alt4

SS2     EIM_D25.alt3

SS3     EIM_D26.alt3

The genarated result from IOMux is:

ECSPI1_MISO   U5    EIM_D17 (ALT4)
ECSPI1_MOSI   V1    EIM_D18 (ALT4)
ECSPI1_RDY    B4    GPIO_19 (ALT5)
ECSPI1_SCLK  U6    EIM_D16 (ALT4)
ECSPI1_SS0    Y3    EIM_EB2 (ALT4)
ECSPI1_SS1    V2    EIM_D19 (ALT4)
ECSPI1_SS2    Y2    EIM_D24 (ALT3)
ECSPI1_SS3    W3   EIM_D25 (ALT3)

SS2 and SS3 are difference, I want to know which document is correct (urgent).

Thank you very much.

Best Regards.

Hi.

the correct answer is SS2 in EIM_D24 & SS3 in EIM_D25 if you check the table 4-3 in the reference manual is also explicit, I think something is not updated in the iomux and maybe is for a diferent TO.

Hope this can help you

Nicolas
