sdhci2 not initialized

[hgalindo]

I'm trying to make the TinyVision board boot from the onboard SD-NAND (I soldered a chip).
Added the sdhci2 structure to the board.c file

sdhci_t sdhci2 = {
        .name = "sdhci2",
        .reg = (sdhci_reg_t *) 0x04022000,
        .voltage = MMC_VDD_27_36,
        .width = MMC_BUS_WIDTH_4,
        .clock = MMC_CLK_50M,
        .removable = 0,
        .isspi = FALSE,
        .gpio_clk = {GPIO_PIN(GPIO_PORTC, 0), GPIO_PERIPH_MUX3},
        .gpio_cmd = {GPIO_PIN(GPIO_PORTC, 1), GPIO_PERIPH_MUX3},
        .gpio_d0 = {GPIO_PIN(GPIO_PORTC, 4), GPIO_PERIPH_MUX3},
        .gpio_d1 = {GPIO_PIN(GPIO_PORTC, 3), GPIO_PERIPH_MUX3},
        .gpio_d2 = {GPIO_PIN(GPIO_PORTC, 2), GPIO_PERIPH_MUX3},
        .gpio_d3 = {GPIO_PIN(GPIO_PORTC, 5), GPIO_PERIPH_MUX3},
};

added the initialization in the syter_boot/main.c file

    if (sunxi_sdhci_init(&sdhci2) != 0) {
        printk(LOG_LEVEL_ERROR, "SMHC2: %s controller init failed\n", sdhci2.name);
        goto _shell;
    } else {
        printk(LOG_LEVEL_INFO, "SMHC2: %s controller v%x initialized\n", sdhci2.name, sdhci2.reg->vers);
    }

    if (sdmmc_init(&card0, &sdhci2) != 0) {
        printk(LOG_LEVEL_WARNING, "SMHC2: init failed\n");
        goto _shell;
    }
  

compiled and flashed to the SD-NAND, this is the output when booting from it

There is not hardware issues as I am able to enable the SD2 on the .dts and use it under OpenWRT (booting from SD Card).

This the output when bootng from SD Card

Am I missing something to initialize the sdhci2 and boot from it?
Thanks.

SDC2 Currently not supported, due to different controller IP, separate driver adaptation is required

[hgalindo]

ok, any idea if it will be adapted?
