Hello
I am working on OMAP-L138 development Board(LCDKOMAP-L138). and linux board is AM5K2E04 board
I want communicate between lcdkOMAP-L138 and AM5K2E04 board using USB.
1.Want to use OMAP-L138 as a device
2.Want to use AM5K2E04 as a Host
So I am able to configure OMAP-L138 as Serial Device and AM5K2E04 as Host device,But the problem is when I am sending data packet from Host to device,Device is unable to receive more than 128Bytes but at host side it is sending the packets.
When i am sending 1 Byte data from host to device then its working fine,Only problem is while sending larger Data packets
i have attached the mini-com Log.it contain both data transmission .
1.While sending 1-Byte data from host
2.While sending 128Bytes data from Host
I am using Ti-processor-sdk-rtos-omapl138-lcdk, in CCS10 . And I have successfully installed the PDK example for LCDKOMAPl138.
and I am using USB_DevMsc_lcdkOMAPL138_armExampleProject example
