Part Number: MSP430F5510
Hello,
Regarding to "SYS18" errata on MSP430F5510, my customer is asking some question.
They are using USB-BSL for writing firmware from PC(via USB) with MSP430_USB_Firmware_Upgrade_Example GUI
(BSL_USB_GUI.exe) on their product line.
But sometimes MSP430F5510 is not connected to PC.
(“No device connected” error massage is shown on TI-GUI.)
After that, firmware was written again correctly to problem device via JTAG and USB function was no problem.
So they have a concern of “SYS18”errata as one of possible cause.
The version of USB-BSL(RAM) which they are using is 00.07.08.38. (I think this version is old.)
(Question)
(1) According to errata,
The cause of SYS18 is that USB registers are unlocked and ACCVIFG is set at start-up.
And we need to use latest version of USB-BSL as workaround.
What is different point between old version BSL and latest version BSL ?
Is it workaround No.4? Is its contents as following?
(Clear the access violation flag at the beginning of the application code(BSL430_Low_Level_Init code).)
Or is there any different point except to SYS18?
(2) About described USB BSL in workaround,
Does this mean RAM-BSL?
Regards,
