I am working on ADSP BF 548 Evaluation board with VDSP++ compiler ver 5.1.2. Here we are using HOLT chip (HI-6136) for MIL1553B protocol, which we are accessing through SPI interface to read/write registers. This SPI communication with HOLT chip is working fine when “Enable Optimization” is disabled under the Project option->Compile->General. But when “Enable Optimization” is enabled, the SPI communication with HOLT chip is not working.
Kindly suggest us, if any other configuration/settings to be done in the code or project settings to overcome this issue at the earliest.
