CA68013A DOWNLOAD *.IIC TO EEPROM(no wave on iic bus)
I tried to download "my_firmware.iic" to my CY68013A board with two bland new 24LC128 EEPROM(A0,A1,A2:1,0,0 and 1,1,0), below is what i did:
1. Open Cypress suit usb 3.4.7->Cyconsole->EZ-USB interface
2.Select download C:\Cypress\USB\Examples\FX2LP\Vend_ax\Vend_ax.hex to CY68013A's on chip RAM
3.Set Req:0xA9, Value:0x0000, index:0x0000, Length:16, Dir:in, i got:CD CD CD CD CD.........
4.Set Req:0xA9, Value:0x0000, index:0x0000, Length:1, Dir:out, hex byte: 00
5.Set Req:0xA9, Value:0x0000, index:0x0000, Length:1, Dir:in, i got:CD again(that means now data be wrote in to EEPROM)
6.Select lg EEPROM->"my_firmware.iic" i got messagebox: EEPROM NOT ENABLED.
7.I used a oscilloscope to IIC BUS during 0xA9 and lg EEPROM, i found there is not wave on the BUS!!!
Is there anybody can help me? Thanks!
