have we detailed docu in SDIO 1.1 / SDIO 2.0 ?
if GPIO15 goes high, there is an other bootloader waiting for what?
why in this mode - if GPIO 0 goes LOW and reboot, no bootloader for SPI Flash is come,
allways a "new face of a NEW Bootloader" ?
can we boot raw data adressed like SPI flash in this mode from SD Card ?
must it be raw data or can it be FAT / FAT16 / FAT32 formated ?
where must write the boot cfg at which adress for this ?
how is the format of this cfg ?
which SD cards are supported generally? SD / SDHC / SDHX ?
1,8 MByte/s in SDIO2 Mode will be verry welcome to boot officially from SD Card
-----------
have we document for supply SDIO Components example LAN Module, High Sensoric Video , other SDIO Module?

thank you for your efforts!
