but what is mean with SDIO 1.1 / SDIO 2.0 and what can we know about in documents from you, are there details availabel?

mean you SDIO Simplified Specification or mean you Physical Layer Simplified Specification SD Cards

this is not clear in the moment, because SDIO is High-Level-Protokol for IO-cards in SD-Slot example WLAN and SDIO is named by µC chips too.

can you clear this, please ? ;-)

thank you!

best wishes

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!
