Hi, when the MSP430F149 gets a little low voltage from a gold cap for some seconds the flash is cleared; the MSP430F149 refuses to work again even after discharging all capacitators and reset! The problem is reproducible on any tested board. What can be done against the flash clearing? Regards Rolf F.

Hi, Does anybody has experience using the msp430F149 as a datalogger, using a sequential flash segments erase and write method within a reserved 16kb flash section (0xB000-0xF000). My concern is the broad-range flash write/erase cycle specification: nominal 100k, but minimal 10k. How realiable is the nominal 100k cycle parameter for field operation, i.e., how many devices are to be exp

Hello All Has any body got any experience or comments on writing to Flash (MSP430169), just before power down. Im my application I am monitoring the input power supply, i.e. input to the 3.3v MSP supply regulator, and when I detect power down write to the user area of Flash (0x1000) the uptime, this flash area will have been pre-erased during initial programming, to reduce the time tak

Hi all, I've got a table that needs to be uploadable over a serial port. But I don't know what the correct way is for me to define the table in the files. I.e. the typedef and the enum never change so should be in flash??, the table should be uploadeble and therefore should remain in flash as well. But for some reason the consume data space. Can anyone tell me what it is that I'm overseein

Hello! I am trying to write in the data flash. There are a couple ot things I don't understand. 1. What is the meaning of FRKEY? I understand FWKEY as a kind of protection so that the flash cannot be easily accidentaly overwritten. Am I right? But what is the point of this when reading? I can directly read what I wrote, for instance like this: #define DATA_FLASH 0x1000 uint8 mydata...

Hi All, I'm a newbie to the group and to MSP430 development... I'm working on an simple battery-powered product that measures sensors with the F149. It uses a simple serial command structure to communicate to the outside world (me). Occasionally the data and code I have stored in flash get's corrupted at runtime. Seemingly random flash segments get initialized to unprogrammed "FF

Hey, Does anyone know how to store and retrieve the contents of an array to and from flash memory in C? In other words, int array[10]; array[(element 0 thru 9)] = (some data stored in flash); Probably simple, I could do it in ASSY, but I'd rather keep it all in C if possible. If you're interested, I'm trying to use a f149 for a Mass Air Flow - sensor based EFI system... A-D the maf a

What do I look for to find out how much memory and code is used in a compiled mspgcc program? I've looked through the .LST file, but it seems to mention only where each segment is located, rather than how much of each is used. When I flash the device the programmer tells me how many bytes are programmed, so I can at least get the flash code size, but still have no way to find the memor

Hallo, ich m?chte flash aus dem RAM heraus programmieren. Ich habe folgendes vor: In main-routine habe ich mein Flash-Programm. Das Flashen soll ?ber RS232 geschehen. Wenn man Flashen m?chte, so wird erst das Flash- Routine in RAM kopiert. Diese Routine programmiert das Flash mit den Daten, die ?ber RS232 kommen. Fragen: 1. Wie kann ich die Flash-Routine ins RAM kopieren. Es w?re supe

I am using an MSP430FG4618 and have found a wealth of information and examples on writing to the flash but very little on reading to it. I have written a program to fill the first half of the flash memory with sensor based data but I would not like to read that data and send it to the PC via UART. The manual does not have any sections specifically regarding reading the memory and my extensive ...

I am trying to implement a couple of C functions to erase an information segment on the MSP430F148 and then write selected words to memory, using the assembly example in the user manual as a guide. The system is resetting, and I am not sure where it is happening. I would appreciate any guidance you can give. The MCLK, set to 2 MHZ, is selected for the flash clock source, divided by

Hi guys, Can any one suggest me an off the shelf file system which can be used on internal flash of msp430F1611(internal flash=48k). I plan to specify some portion of it with some thing like const char harddisk[16k]; and then start my file space at first byte of this harddisk. Any suggestions in this regard ....

Hi! Did anyone try to program the MSP Flash Memory (program) remotely ? Could it be done by software ? In this last question I mean send program information to the MSP storing it into a ram or External Flash and then programming this code into MSP flash.
