USB OTG Peripheral/Function on DM37xevm board and AM3517evm Board??

H@fiz

Other Parts Discussed in Thread: AM3517

I have working High Speed USB Host (I am not referring High Speed OTG Host ) on AM3517evm and AM/DM37xevm boards

1. Is High Speed USB OTG (Peripheral/Function Mode) also same on both boards?

2. There is no Register Manual for USB OTG in DM37xevm Technical Reference Manual. How to get it?

3. On DM37xevm board, OTG Peripheral mode is using NXP ISP 1507 transceiver. Is it right?

4. On am3517evm board, we have a register LVL_INTR_CLEAR at 0x48002594 to clear USB Interrupts. It is missing on dm37xevm?

Hi,

1. Both processors use the same High-Speed USB OTG Controller, which is an instantiation of the MUSBMHDRC from Mentor Graphics Corporation.
2. If you are indeed working in Mentor Graphics you should be able to get this specification internally.
3. Yes.
4. See 2.

Thanks for you answers Biser

1. I am of course have Mentor OTG Specifications internally :-) but I am referring to TI specific Register set. For example See 20.1.14 article in am3517evm Reference manual.
2. Again, there is a register "CONTROL_LVL_INTR_CLEAR" at page 776, article 6.6.4.69 in am3517 reference manual to clear USB interrupt. Have we alternate register in dm37xevm platform.
3. Is High Speed USB OTG (Peripheral/Function Mode) same on omapl138evm, am1808exp, am3517evm and dm37xevm.

1. There are no TI specific registers besides the ones listed.
2. I can find no corresponding register
3. OMAP1x, AM1X and DM37X are not supported on this forum.

Hi,

If DM37xevm does not lie under this forum then kindly send me the link.
