Download firmware in EEPROM requests
I have some problems to reenumerate my CY7C64713, si I just try to write the first bits: 'C0 04 B4 03 10 00 00 00' through a .iic file. I'm certainly wrong about the way to write it in the EEPROM but as I read in some example program and in some article in the site I may need to use another request as A2 or A6 or A9 (i'm not using a large EEPROM).
In my program which upload the "firmware" I reset the 8051 an hold it off (by writting 1 in the address 0xE600 with the request A0, this works fine) then I send the firmware (using the command 'write' of the CyAPI at the address 0x0000). I turn on the 8051 and use the ReConnect command.
But even if I unplug and reconnect the device I don't have the good enumeration.
As I read:
in the technical reference manual I first want to ask what are the different 'Ax' commands?
