ADSP-21489 SHARC SPI slave booting

Hi ADI's


one of my customer having some trouble booting ADSP-21489 in SPI slave mode using a host microcontroller.

The customer tries to boot the ADSP-21489 into slave mode after connecting SHARC EVM and STM MCU to SPI.

Customers use Sigma Studio for SHARC as their development environment.

First, connected Sigma Studio and ADSP-21489 to download the ldr file and confirmed that it is booting without problems. (in slave mode)
But connecting STM MCU with ADSP-21489, tried it but it did not work normally.

customer confirms that the STM MCU is communicating with the ADSP-21489.


Is there any data to send before downloading the ldr file after the first Rest?

Is there a way to check if the ldr file is loaded normally from the MCU to the DSP?


Thank you
