My PC couldn't detect the cy7c67300 after I loaded the msc firmware into EEPROM.The usb device in the bottom right corner of PC windows is missing!The following steps are my loading process.
1.[cy]$ cd Source/stand-alone/msc
2.[cy]$ make clean all
3.[cy] $ make
4.[cy]$ make clean wrap
The result is that the PC couldn't detect cy7c67300 after I did as the bash prompt told me to reset the button on the board. I have no idea about it,can you help me?
When you say MSC firmware I assume you're talking about CY4640 firmware for Ez-Host. This configures Ez-Host as a mass storage host.
Are you using this firmware "as is" or made any modifications to it?
I have read ANI5484 and AN70973 in the www.cypress.com and I want to use cy7c67300 to read data from an USB Flash Drive, my development board is a custom board. I used the msc firmware of the cy4640 development kit without any modifications.I have found the source code at the USB/OTG—Host/Source/stand-alone/msc,and I used the gun tools to build it and loaded it into the EEPROM! But the PC can't identify the usb device(cy7c67300,vid=04B4,pid=7200) after I did it. To my surprise,I have tried to load other example codes in the USB/Host/Source/stand-alone,and the result is same as msc firmware,the usb device was missing unexpectedly after the code was loaded into EEPROM！I really don't know about this,could you help me?
