Hello.
I have a shiney new OMAP-L138 EVM board. The OMAP-L138 includes an SDIO interface and the EVM board provides access to the SDIO interface. I am attempting to use a Bluetooth radio via the SDIO interface. I'm using DaVinci-PSP-SDK-03.20.00.06 (linux 2.6.31). I've built the kernel with bluetooth and sdio support.
Here's a non-radio question, but I would be greatful for any feedback... When I insert the SDIO card, I would expect udev to register some event, but I see none ($ udevadm monitor --env). Am I correct that udev should detect the insertion?
I have several kernel modules that are relavent, but some remain a mystery. Here is an abriviated list of kernel modules from lsmod:
btsdio 4752 0
hci_vhci 5288 0
mmc_block 10392 0
davinci_mmc 9828 0
sdhci_pltfm 3064 0
sdhci 16812 1 sdhci_pltfm
mmc_core 55988 5 btsdio,sdio_uart,mmc_block,davinci_mmc,sdhci
Can you please help me understand which of these drivers are required?
Is the sdhci_pltfm driver necessary?
I wish my questions were more pointed, but I think I'm missing some pretty basic information.
If I wanted to create device nodes under /dev, what major and minor numbers would I use for sdio? The devices.txt file in the Documentation folder indicates that an MMC device is a block device with major number 179. Does sdio use the same major number?
Does anyone have experience using SDIO-Bluetooth that they wish to share?
Thank you very much,
Chris
