One of my customers is having trouble slave booting the ADSP21489..

I have been discussing this with ADI 's process support team for a long time and I have been advised to leave a message in this forum.

 

The customer wants to slave boot the EVB's ADSP-21489 with SPI communication using STM's MCU.

However, slave booting of the ADSP-21489 does not seem to be working properly.

 

summarize the current situation briefly.

1. Transfer LDR data from MCU and send back xxx_IC_y.h (Reset + Version Information + Schematic Code + Parameters) data from MCU again
-> NG: LED 1, 2, 3, 4 of Ez-Kit lights up, but large noise in Ez-Kit is output together with Audio Signal
2. Transfer LDR data from MCU and send xxx_IC_y.h (Reset + Version Information + Schematic Code + Parameters) data to SigmaStudio (3.14)
-> NG: LED 1, 2, 3, 4 of Ez-Kit lights up, but large noise in Ez-Kit is output together with Audio Signal
3. Transfer LDR data from SigmaStudio (3.14) and send xxx_IC_y.h (Reset + Version Information + Schematic Code + Parameters) data from MCU
-> OK: Audio signal is output without any problem.

 

The current status is as above.
What should I do?

 

Thank you
