devram_SLDU007.gifFigure 11. DEVRAM Target Options

To Program to DEVRAM:

  1. Change the code range to the DEVRAM memory space.
    1. Right click on Target 1 in the project window, and select Options for Target.
    2. Go to the BL51 Locate tab, and modify the Code Range to go from 0x2000–0x3FFF.
  2. Copy the following to the Code box:

    3. ?pr?external1_ISR?PGA450_isrs (0X2100),
    ?pr?timer0_ISR?PGA450_isrs (0X2400),
    ?pr?timer1_ISR?PGA450_isrs (0X2800),
    ?pr?serial_ISR?PGA450_isrs (0X2C00),
    ?pr?linPID_ISR?PGA450_isrs (0X3000),
    ?pr?linSciRxData_ISR?PGA450_isrs (0X3400),
    ?pr?linSciTxData_ISR?PGA450_isrs (0X3800),
    ?pr?external0_ISR?PGA450_isrs (0X3900),
    ?pr?linSync_ISR?PGA450_isrs (0X3D00)

  3. Comment out the OTP section in STARTUP.A51, and uncomment the OTP section
    1. An example of this is shown in Figure 13.
otp_SLDU007.gifFigure 12. OTP Target Options

To Program to OTP:

  1. Change the code range to the OTP memory space
    1. Right click on Target 1 in the project window, and select Options for Target.
    2. Go to the BL51 Locate tab, and modify the Code Range to go from 0x0000–0x1FFF.
  2. Delete everything in the Code box.
  3. Comment out the DEVRAM section in STARTUP.A51, and uncomment the OTP section.
    1. An example of this is shown in Figure 14.

Instructions: Build the PGA450.uvproj to generate the custom .HEX file used to program the internal 8051 core. The LIN Demonstration using PGA450Q1EVM Firmware Rev 2.1 provides instructions on how to upload the .HEX file using the EVM GUI.
