I use a 21469 on my own plateforme.
I try to use spi bootloader in spi master mode.
I compile my application with the default kernel.
But when I reset the board, the DSP does not look like running.
in VDSP help file, I can read
Master Header Information
The read opcode is fixed as 0xC0 (LSBF format) and is 24-bits long. The 8-bits that are received following the read opcode should be programmed to 0xA5 (see Figure 20-10). If the 8-bits are not programmed to 0xA5 the master boot transfer is aborted.
I don't really understand where I should find these bytes in the ldr file, but when I reset the board and connect the emulator, I can read the first bytes in program memory: A5 00 00 00.
If I suppress from the file A5000000, then the code is correctly download, but the bootloader is not executed.
