Part Number: MSP430FR2675
I am working on updating the MSP430FR2675 FW via I2C using the msp430-i2cbsl-tool tool. I am sending this command "./msp430-i2cbsl-tool -i /dev/i2c-0 -s a -f Cerberus.txt" and I get the following error.
--------------------------------------------------------------- TI MSP430 I2C Linux BootLoader 01.00.00.00 --------------------------------------------------------------- INFO: I2C BUS /dev/i2c-0 specified INFO: Slave address 0xa specified INFO: Firmware file Cerberus.txt specified INFO: Opening TI-TXT firmware file firmware.txt... done!

ERROR: When trying to invoke or unlock device (Response code 0x108).
After doing that command, I can no longer communicate with the MSP430 until I reset it. This makes me think that the unit is actually entering BSL mode, but the tool is not recognizing that it is. My code to enter BSL mode is below:
uint8_t HostInterface_enterBSLMode[HOST_INTERFACE_BSL_CMD_SIZE] =
{0xCA, 0xFE, 0xDE, 0xAD, 0xBE, 0xEF, 0xBA, 0xBE};
// Check if BSL mode is needed to be entered
if (HostInterface_i2cDataBuffer[HOST_INTERFACE_REG_OFFSET] == HostInterface_enterBSLMode[0])
{
int index;
bool enterBSLMode = true;
for (index = 1; index < HOST_INTERFACE_BSL_CMD_SIZE; index++)
{
if (HostInterface_i2cDataBuffer[index + HOST_INTERFACE_REG_OFFSET] != HostInterface_enterBSLMode[index])
{
enterBSLMode = false;
break;
}
}
if (enterBSLMode == true)
{
// Clear interrupts before firmware load
__bic_SR_register(GIE);
// Jump to BSL
((void (*)())0x1000)();
}
}
Is there something I need to change or fix?
