Hi,
I have connected a SD slot for to insert a wireless module on pins SD2:
I set mx53_loco.c as follows:
-------------------------------------------------------------------------------
/* SD2 */
+ MX53_PAD_SD2_CLK__ESDHC2_CLK,
+ MX53_PAD_SD2_CMD__ESDHC2_CMD,
+ MX53_PAD_SD2_DATA0__ESDHC2_DAT0,
+ MX53_PAD_SD2_DATA1__ESDHC2_DAT1,
+ MX53_PAD_SD2_DATA2__ESDHC2_DAT2,
+ MX53_PAD_SD2_DATA3__ESDHC2_DAT3,
-static struct mxc_mmc_platform_data mmc3_data = {
+static struct mxc_mmc_platform_data mmc2_data = {
.ocr_mask = MMC_VDD_27_28 | MMC_VDD_28_29 | MMC_VDD_29_30
| MMC_VDD_31_32,
- .caps = MMC_CAP_4_BIT_DATA | MMC_CAP_8_BIT_DATA
- | MMC_CAP_DATA_DDR,
+ .caps = MMC_CAP_4_BIT_DATA,
.min_clk = 400000,
- .max_clk = 50000000,
- .card_inserted_state = 0,
+ .max_clk = 1000000,
+ .card_inserted_state = 1,
.status = sdhc_get_card_det_status,
.wp_status = sdhc_write_protect,
.clock_mmc = "esdhc_clk",
mxcsdhc1_device.resource[2].start = gpio_to_irq(SD1_CD);
mxcsdhc1_device.resource[2].end = gpio_to_irq(SD1_CD);
- mxcsdhc3_device.resource[2].start = gpio_to_irq(SD3_CD);
- mxcsdhc3_device.resource[2].end = gpio_to_irq(SD3_CD);
+ mxcsdhc2_device.resource[2].start = 0; // no SD irq
+ mxcsdhc2_device.resource[2].end = 0;
mxc_cpu_common_init();
mx53_loco_io_init();
mxc_register_device(&mxc_pwm2_device, NULL);
mxc_register_device(&mxc_pwm1_backlight_device, &mxc_pwm_backlight_data);
mxc_register_device(&mxcsdhc1_device, &mmc1_data);
- mxc_register_device(&mxcsdhc3_device, &mmc3_data);
+ mxc_register_device(&mxcsdhc2_device, &mmc2_data);
mxc_register_device(&mxc_ssi1_device, NULL);
mxc_register_device(&mxc_ssi2_device, NULL);
mxc_register_device(&mxc_alsa_spdif_device, &mxc_spdif_data);
-------------------------------------------------------------------------------------
With this changes i not view eth1 when i inserted for example an SD on my slot connected on SD2 pin.
Do you have any advice?
thanks for answers
