Re: VS1010 and eMMC

Hi Panu, Unfortunately, there is a hardware error. The CMD and CLK lines on the eMMC are swapped so this design was never going to work. It's a tight design but jumping the copper over to right orientation should be possible and I will try that tomorrow. Attached is an image from Toshiba on the init...

VS1010 and eMMC

Hello, I've used the VS1010 with an eMMC in a design but there seems to be a communication issue between them. The VS1010 will send clock and commands to the eMMC but there is either no response or an incorrect response so higher clock speeds are not achieved. The initial clock frequency from the VS...

Re: VS1010 Battery Charging

Hi Panu,

That bit of code worked! It seems that the setting value will dictate how much current is drawn from the source. The IC draws current first and whatever is left is sent to the battery via VHIGH as you said.

Thanks for the help! I'm sure I'll have many more questions :)

Re: VS1010 Battery Charging

Hi Panu! Thanks for the response. So the reason I attempted to use USBVDD as the charger output is because of the block diagram of the VS1010 but also because when I placed USB power at USBVDD and the battery at VHIGH, the battery did not charge. The current consumption was actually independent of p...

VS1010 Battery Charging

Hello, I'm using a VS1010 dev board to validate some design choices for a product. One of them is to use the VS1010 battery charging capabilities to charge an internal Li-po battery. I have a few questions about this: 1. The datasheet shows USBVDD as a power input in the "5.5 VS1010d VQFN-68 Pin Des...
