   I have a application doing well in non-secure mode using SPI master mode and UART slave mode.

   Then I locked the processor,the same application wiht blx format process well using SPI master mode.But using UART slave mode was failed.I send "@" and received four bytes,then i send whole ldr but nothing happend(the program starts running often flashing led lights.) 

   I would like to know what else i need to do.
