Other Parts Discussed in Thread: MAX3386E, UNIFLASH
Hi,
i try to get the BSL running with invocation through my application software.
I got a board with a MAX3386E RS232 converter on it connected to eUSCI_A0. According to SLAU622G section 3.3.1 it's possible.
I've included the following code into my application software, which is called by a command over the serial connection.
#include "msp.h"
#include <ti/devices/msp432p4xx/driverlib/driverlib.h>
...
#define BSL_PARAM 0xFC48DFFF // I2C slave address = 0x48, Interface selection = UART
//#define BSL_API_TABLE_ADDR 0x00202000 // Address of BSL API table
#define BSL_ENTRY_FUNCTION (*((uint32_t *)BSL_API_TABLE_ADDR))
...
main()
{
...
if (status & STATUS_BSL)
{
status &= ~STATUS_BSL;
MAP_Interrupt_disableMaster();
NVIC->ICER[0] = 0xFFFF;
NVIC->ICPR[0] = 0xFFFF;
NVIC->ICER[1] = 0xFFFF;
NVIC->ICPR[1] = 0xFFFF;
((void (*)())BSL_ENTRY_FUNCTION)((uint32_t)BSL_PARAM); // Call the BSL with given BSL parameters
}
...
}
When i now try to enter the BSL, the MCU leaves my application software ( doesn't respond to my commands on the serial) but the BSL_scripter can't establish a connection to the device. With a scope i can see the Signals comming from the Scripter, but no answer from the device.
When i use a brand-new MCU or a Device which got reset to factory defaults, it works.
The BSL_Scripter ist startet out of a cmd-window like the following
C:\EigeneDaten\Workspace_v7\Datenlogger\Debug>C:\EigeneDaten\Datenblaetter_u_sonstiges\MSP_Doku\MSPBSL_Scripter_win\BSL-Scripter.exe -d -g -n P4xx -i [COM1,UART,9600,PARITY] -b -z [RESET]

BSL Scripter 3.3.0
PC software for BSL programming

---------------------------------------------------------
Log mode is turned off!
C:\EigeneDaten\Datenblaetter_u_sonstiges\MSP_Doku\MSPBSL_Scripter_win\BSL-Scripter.exe -d -g -n P4xx -i [COM1,UART,9600,PARITY] -b -z [RESET]
Verbose is turned on!
Device : P4xx
Init communication parameters : [COM1,UART,9600,PARITY]
[ERROR_MESSAGE]Initialization of P4xx BSL failed! Exit the scripter!
I got no idea left why it does not work correctly.
