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?
