Invoking the BSL on a MSP430F5510

Joao Simoes

Hello,

I am trying to work with a custom board design (done by someone else) which has a MSP430F5510IRG with a USB connection. I was wondering if it is possible to invoking the BSL by using any of the PINs listed below? (The board has no connections to the TEST/SBWTCK and nRST/NMI/SWSTDIO PINs, so I cannot use the JTAG and Spy-by-wire interfaces).

P1.0/TA0CLK/ACLK

P1.1/TA0.0

P1.2/TA0.1

P1.3/TA0.2

P1.4/TA0.3

P1.5/TA0.4

P1.6/TA1CLK/CBOUT

P1.7/TA1.0

PJ.0/TDO

PJ.1/TDI/TCLK

PJ.2/TMS

PJ.3/TCK

P4.0/PM_UCB1STE/PM_UCA1CLK

P4.1/PM_UCB1SIMO/PM_UCB1SDA

P4.2/PM_UCB1SOMI/PM_UCB1SCL

P4.3/PM_UCB1CLK/PM_UCA1STE

P4.4/PM_UCA1TXD/PM_UCA1SIMO

P4.5/PM_UCA1RXD/PM_UCA1SOMI

P4.6/PM_NONE

P4.7/PM_NONE

P6.0/CB0/A0

P6.1/CB1/A1

P6.2/CB2/A2

P6.3/CB3/A3

Thanks a lot!

TI factory HID BSL can be invoked with PUR pin / button during power-up. If this is not possible, than last main flash segment can be erased, and if during power-up 0FFFFh word is at 0FFFEh address, BSL should be invoked during power-up by default without any other action.

Hello,

"If this is not possible, than last main flash segment can be erased, and if during power-up 0FFFFh word is at 0FFFEh address, BSL should be invoked during power-up by default without any other action."

Can you please explain how can this be done?

Thank you!

By device firmware, if this option exist.
