TDA4VE-Q1: online sysconfig tool generating wrong .dtsi

one and zero
Mastermind 18136 points
Part Number: TDA4VE-Q1
Other Parts Discussed in Thread: SYSCONFIG

Tool/software:

Hi champs,

it looks like the online sysconfig tool is generating the wrong offset address for WKUP_PADCONFIG registers:

from datasheet

ball B25: MCU_SPI0_D1
PADCFG:
WKUP_PADCONFIG_42
0x4301C0A8

from generated .dtsi file

J721S2_WKUP_IOPAD(0x040, PIN_INPUT, 7) /* (B25) MCU_SPI0_D1.WKUP_GPIO0_69 */

Thanks and kind regards,

one and zero

    Hello,

    The generated .dtsi will contain address offsets specific to Linux. This is because the device .dtsi splits the WKUP pinmux region into four different regions. Please see https://git.ti.com/cgit/ti-u-boot/ti-u-boot/tree/arch/arm/dts/k3-j721s2-mcu-wakeup.dtsi.

    Here are the four regions and respective adjustments.

    • 0x4301C000: no adjustment
    • 0x4301C038: .dtsi offset = offset from 0x4301C000 - 0x038
    • 0x4301C068: .dtsi offset = offset from 0x4301C000 - 0x068
    • 0x4301C190: .dtsi offset = offset from 0x4301C000 - 0x190

    In this case, WKUP_PADCONFIG_42 belongs to the third region and therefore has an effective offset of 0x040 in the generated .dtsi.

    Regards,
    Mark
