I´m trying to get my program from SigmaStudio 4.4 to the EEPROM connected to my ADAU1452.
The DSP is connected via the I²C-Slaveport to the PC.
The EEPROM (25AA1024) is connected via SPI-Masterport
Selfboot is turned off (LOW).
ADDR0 & ADDR1 are also Low.
The connection to the DSP works fine. I can read and write all the registers.
But if I try to use the "Write Latest Compilation through DSP" funktion, it doesnt work.
The I2C-connection is working fine but the SPI-comunication doesnt start (no movement on the Master SPI pins)
Supply voltage is Stable.
Did I forget any configuration?
Thanks in advance
Hello! There is a possibility that the EEPROM does not work. Try to replace this chip and repeat the procedure.
I measured all the pins of the EEPROM. They are fine.
Then I desoldered the EEPROM but nothing changed .
I also measured all supply pins on the DSP. Also fine.
Edit: I got the SPI_M_pins to change logic level when selected as multipurpose pins(so they can´t be completely dead).
They are also configured the right way when the DSP loads the I2C-to-SPI program.
