Hi~ A few months ago I bought two CYUSB3KIT-003 Cypress Development Kits.

   

I try to learn GPIFII transmission function and try run Designing a GPIF™ II Master Interface example(application note: AN87216)

   

FX3 Back-to-Back Setup Using CYUSB3KIT-003 like  AN87216 Figure 26.

   

I test Master transform data to Slave was Pass (FX3 Firmware Master = Autoslave.img   Slave = AutoSlave.img) 

   

For example, Master-side transfer data 0x64 0x65 0x66 0x67 0x68 0x69 0x6A 0x6B total of 8 Bytes to Slave.

   

Slave-side Receives the correct data from Master.

   

But test Slave transform data transform data to Master was Fail.

   

For example, Slave-side transfer data 0x64 0x65 0x66 0x67 0x68 0x69 0x6A 0x6B total of 8 Bytes to Master.

   

But Master-side Receives the error data from Slave. And can not be expected.

   

What can I do for next step??

Hi,

   

Did you check if the flag / other control signals behave as expected? There could be a connection issue in any of these crucial signals.

   

Just in case, please create a Tech Support case with us so that one of our engineers can investigate the issue.

   

Regards,
