| This example project uses the high speed CRC feature of the RL78. | ||
|
|
||
| It has been tested on the RL78G14 TB (64K device, R5F104LE) | ||
|
|
||
| The project is for IAR Embedded Workbench. | ||
|
|
||
| After the aplication started, LED1 keeps blinking to show the code has been flashed correctly and is working past the CRC calculation stage. | ||
|
|
||
| If the CRC calculation is correct, LED2 gets turned on. | ||
|
|
||
|
|
||
| The settings for IAR Workbench to calculate the checksum are as follows: CRC16 (0x11021 polynomial), size 2, keep complement 'as is', MSB first, 32-bit checksum unit size, initial value 0x0 | ||
|
|
||
| This is equivalento to the following settings made in the linker script: | ||
|
|
||
| -J2,crc16,L,,CHECKSUM,,0x0=0x0-0xFFFB | ||
|
|
||
|
|
||
| The checksum is placed in location 0xFFFC-0xFFFD | ||
|
|
||
| -Z(CONST)CHECKSUM=0xFFFC-0xFFFD | ||
|
|
||
|
|
||
| The high speed CRC sum is computed over flash range 0x0 t0 0xFFFB | ||
|
|
||
| -Hff -h0x0000-0xFFFB | ||
|
|
||
|
|
||
|
|
||
|
|
||
| The project can be flashed via the renesas flash programmer software. | ||
| A workspace and project for the renesas flash programmer is placed in the TB_flash folder, to flash the application using the E1 emulator. | ||
|
|
||
| However the E1 emulator cannot be used for debugging within IAR since the rom monitor firmware is included in the last 512/256 bytes of the flash and conflicts with the CRC signature placement in the last 4 bytes of the flash. |
