    Hello HongKe,

    The UART bootloader should work with a tool on PC side (HyperTerminal, TeraTerm, etc). The protocol used in the bootloader is Y-Modem. The file format is binary rather then HEX format (Intel, or Motorola etc).

    Regards,

    Hi，QJ Wang，
    Thanks for your reply. I did use HyperTerminal and the protocol used in the bootloader is Y-Modem,other settings of HyperTerminal is same to the sheet spna193(UART BOOTloader for Hercules TMS570ls31xMCU)，the setup is 115200 8-N-1.The item is successful except 1 and 2. When running the bootloader I can't download the app.The problem appears when running the code of flash operation(uint32_t Fapi_BlockErase( uint32_t Bank, uint32_t ulAddr, uint32_t Size)).I reupload a clear picture ,please help me to see what cause the error.I guess something is wrong with F021_API_CortexR4_BE.lib.But I don't know why.Besides,how can I  generate the .bin file ?
