Problems downloading sections ldr into SDRAM via UART0. TXD and HWAIT pull up. To initialize the PLL, SDRAM and UART (after initializing PLL) used the code from the folder \ldr\init_code\c\ADSP-BF527 EZ-KIT Lite
After downloading the init section HWAIT stand up, and loading halt. If the ldr file does not contain a link against in the areas of SDRAM, the download is completed successfully.
What could be wrong?
