Restoring Texas Instrument TMS320F2806PZA MCU Flash OUT File needs to unlock the protection over dsp microcontroller tms320f2806pza flash memory, and extract the firmware code out from tms320f2806pza microprocessor memory;
The Enhanced USART module can receive a Break character in two ways.
The first method forces configuration of the baud rate at a frequency of 9/13 the typical speed. This allows for the Stop bit transition to be at the correct sampling location (12 bits for Break versus Start bit and eight data bits for typical data).
The second method uses the auto-wake-up feature described in Section 16.3.4 “Auto-Wake-up on Sync Break Character”. By enabling this feature, the EUSART will sample the next two transitions on RX/DT, cause an RCIF interrupt and receive the next data byte followed by another interrupt.
Note that following a Break character, the user will typically want to enable the Auto-Baud Rate Detect feature. For both methods, the user can set the ABD bit before placing the EUSART in its Sleep mode to crack locked mcu tms320f28069 flash memory protection.
The following sequence will send a message frame header made up of a Break, followed by an auto-baud Sync byte. This sequence is typical of a LIN bus master.
- Configure the EUSART for the desired mode.
- Set the TXEN and SENDB bits to set up the Break character.
- Load the TXREG with a dummy character to initiate transmission (the value is ignored).
- Write ‘55h’ to TXREG to load the Sync character into the transmit FIFO buffer.
After the Break has been sent, the SENDB bit is reset by hardware. The Sync character now transmits in the preconfigured mode to break dsp controller tms320f2806pza memory. When the TXREG becomes empty, as indicated by the TXIF, the next data byte can be written to TXREG.
