Ok, figured out this problem you were having. The Java usage that is printed to the screen is actually deprecated - the [mote] ID should be removed. Instead of <java app> [mote] [command], it should be <java app> [command]:
java com.rincon.flashbridgeviewer.FlashViewer -ping instead of java com.rincon.flashbridgeviewer.FlashViewer 0 -ping java com.rincon.flashbridgeviewer.FlashViewer -read 0 0x100 instead of java com.rincon.flashbridgeviewer.FlashViewer 0 -read 0 0x100 etc.. Then, it should work as downloaded. And yes, if the mote ID is put in there then that index should be altered in the Java code in order for the Java app to find the location of the command, so what you did was correct: you fixed the code to conform to the way the Java usage was described, so if that works, it works! I'll update the CVS files to reflect the correct java command line usage, removing the mote ID from the CLI. Background... This was initially written so you could have multiple motes sitting off on the side of the computer and a TOSBase-like mote attached to the computer. In that case you'd need a mote ID to specify which mote to talk to. I dropped that functionality because of potential packet loss that I didn't want to program for, so now you just have the mote attached directly to the computer and no mote ID is required. -David -----Original Message----- From: Munaretto, Daniel [mailto:[EMAIL PROTECTED] Sent: Friday, August 04, 2006 2:22 AM To: David Moss Subject: RE: for David Moss: error found!!

You're using an older version of TinyOS aren't you? TinyOS 1.1.7 uses a PageEEPROM interface defined in the /platform/mica directory, while future versions use a PageEEPROM interface defined in /tos/lib/Flash/AT45DB. The 1.1.7 PageEEPROM interface version defines these crc commands: command result_t computeCrc(eeprompage_t page, eeprompageoffset_t offset, eeprompageoffset_t n); event result_t computeCrcDone(result_t result, uint16_t crc); while future versions define an extra command, thanks to Johnathan Hui, that allows a running CRC: command result_t computeCrc(eeprompage_t page, eeprompageoffset_t offset, eeprompageoffset_t n); command result_t computeCrcContinue(eeprompage_t page, eeprompageoffset_t offset, eeprompageoffset_t n, uint16_t crc); event result_t computeCrcDone(result_t result, uint16_t crc); This can be fixed on your system, but you need to update your version of PageEEPROMM module and PageEEPROM interface. I've attached the updated versions of PageEEPROM files (with a slight fix to make it work with 1.1.7). Put these files in your local compile directory (in either /Blackbook5/apps/FlashBridge where you were compiling from, or in /Blackbook5/media/AT45DB) so you don't overwrite the original 1.1.7 versions. When you compile, these files will override the files in the /platform/mica directory. Incase updating the PageEEPROM component doesn't work, you can remove the latest version by deleting the files from the local directory without breaking your TinyOS. Hope that works. Let me know how it goes. -David -----Original Message----- From: Munaretto, Daniel [mailto:[EMAIL PROTECTED] Sent: Thursday, August 03, 2006 8:08 AM To: David Moss Cc: tinyos-help@Millennium.Berkeley.EDU Subject: RE: for David Moss: [Tinyos-help] Help with real node behaviour!Micaz,tinyos 1.x I have a problem on compiling..i download all useful files but i have a problem about one in particular.

Daniele -----Original Message----- From: David Moss [mailto:[EMAIL PROTECTED] Sent: Wed 8/2/2006 5:22 PM To: Munaretto, Daniel Cc: tinyos-help@Millennium.Berkeley.EDU Subject: RE: for David Moss: [Tinyos-help] Help with real node behaviour!Micaz,tinyos 1.x I have done a lot of work in this area because my projects require flash. Flash memory *is* EEPROM. On your micaz you do have 128kB of ROM memory for your actual binary program on the chip, which you don't have access to. 512kB external flash memory can store data and whatever else you want on, and 4kB of RAM memory for variables/arrays to run your program. For simple logging, check out http://www.tinyos.net/tinyos-1.x/doc/tutorial/lesson8.html This will append bytes to the flash and allow you to read them back. It sounds like, because you're copying full buffers into flash for temporary storage, you may need something a little different than the logging functionality. It's easier to implement a temporary storage on flash than a permanent storage that is retained after reboot because you don't have to deal with finding the write location after a reboot; instead, you can erase the pages of flash you'll use when the mote boots up and start your app writing at 0x0 each time. The AT45DB flash on a micaz can do page-level erases, meaning you erase 256 (+8 extra bytes/page) each time you want to erase data. When you write to the AT45DB, the data actually goes into a physical RAM buffer on the chip before being stored to flash. That means your data won't actually get written until you flush it to flash. Here's a little background on the way flash writes. The process of writing on the AT45DB is usually a read-modify-write, which is different than standard NOR-flash behavior in that the data from a page is first read into its RAM, the data is modified, the page is erased, and the modified data is written back to flash. This prevents data from being corrupted. Standard NOR-flash behavior is 1's turn into 0's on write, and 0's turn back to 1's on erase. So if you wrote 01101101 to a byte on a NOR-flash (like the STM25P on tmotes) and then wrote a 10010011 to that same byte location, you'd end up with 00000001 - not what you'd expect. The AT45DB's read-modify-write prevents this from happening at the expense of time and energy. If you look at the power consumption plot I attached, you can see this behavior (as well as the required energy!) for a few page writes. The flat line is a read, the squiggly lines are writes. Note that the current gets up to 70 mA - you'll need some good batteries (not coin cell) to supply that kind of instantaneous current. With all that said, you can try the PageEEPROM component to do all that, but I recommend trying out the component I wrote to do kind of what you're doing, found in the TinyOS 1.x CVS under /contrib/rincon/apps/FlashBridge. The FlashBridge component is meant to be a library that you can use in any application to directly access flash. You'll need to download most of that /contrib/rincon directory to get the demo apps working (including /tos/lib/Transceiver, /tos/lib/State, and /tools/java/com/rincon/flashbridgeviewer if you want to read the raw flash onto your computer screen) and you'll need to modify the Makefile to include the AT45DB directory instead of STM25P. To try it out, compile and install the FlashBridge component onto your micaz. Then, you can connect to the micaz using serial forwarder and use the Java FlashBridgeViewer app to interact with the flash and get an idea of its behavior. The readme is provided in the /contrib/rincon/apps/FlashBridge/apps/FlashBridgeViewer directory, and part of it is copied below. If you're working with a buffer of data that needs to be stored on flash, I'd recommend breaking them up into 256-byte segments to make them easy to read/write in page increments. Let's say you only need to store a few buffers of data on flash. On boot, erase the first page of flash (this isn't good for wear-leveling, but you probably won't reboot 100,000+ times either): call FlashBridge.erase(0); This will erase the entire first sector - 256 pages of flash, or 256*256=65536 bytes (~1 second erase time). When you issue a command on flash, wait for the event to come back before issuing another command. Now you can start writing at 0x0: uint8_t buffer[256]; // Here's your buffer of data you want to store to flash uint32_t flashWriteAddress = 0; // the next location to write to on flash void writeToFlash() { call FlashBridge.write(flashWriteAddress, &buffer, sizeof(buffer)); // Write the entire buffer to flash. } // Wait for the event to come back.... event void FlashBridge.writeDone(uint32_t addr, void *buf, uint32_t len, result_t result) { if(result) { // SUCCESS! update our write location to the next page, or something. // Note that if we only erased sector 0 on boot, anything after address 0x10000 (the 257'th page on flash) // may not be valid to write to flashWriteAddress += len; } } The FlashBridge component extends the PageEEPROM component incase you want to try to use the PageEEPROM component directly. Then you can check out how it works in FlashBridge's AT45DB implementation. You'll have to write you own apps to get the data onto and off of flash. Hope that gets you started, -david // readme.txt First let's take a look at what commands we have available from the FlashBridge. Compile FlashBridgeViewerTest or BlackbookConnect or something to the mote and connect to the mote with your serial forwarder. Then... $ flashbridge No arguments found Usage: java com.rincon.flashviewer [mote] [command] COMMANDS -read [start address] [range] -write [start address] [22 characters] -erase [sector] -flush -crc [start address] [range] -ping Let's ping the mote to see if we have FlashBridgeViewer installed: $ flashbridge -ping Pong! The mote has FlashViewer installed.

The FlashBridge itself lets you write as much data at a time as you want, but our TOS_Msg's being passed back and forth over UART only hold so much. And there's not much you can specify on the command line anyway, so here's what happens: $ flashbridge -write 0x0 hello_flashbridge! Writing data 0x68 0x65 0x6c 0x6c 0x6f 0x5f 0x66 0x6c 0x61 0x73 0x68 0x62 0x72 0x69 0x64 0x67 0x65 0x21 SUCCESS: 18 bytes written to 0x0 We'll read 0x20 bytes back from 0x0 to make sure what we wrote exists: $ flashbridge -read 0 0x20 0x0 to 0x20 _________________________________________________ 68 65 6C 6C 6F 5F 66 6C 61 73 68 62 72 69 64 67 | hello_fl ashbridge 65 21 FF FF FF FF FF FF FF FF FF FF FF FF FF FF | ! Keep in mind that the AT45DB flash doesn't necessarily put what you wrote onto the physical flash until you flush it out, so here's how you flush: $ flashbridge -flush SUCCESS: Flush complete We can take the CRC of the data we just wrote: $ flashbridge -crc 0x0 18 SUCCESS: CRC is 0x6D3F And we can erase the entire sector. FlashBridge was designed for sector erases, which you can actually go in and edit if you want - but it's not entirely recommended. The ST M25P80 flash erases in sector-lengths, which is 64kB at a time. Atmel's AT45DB flash chip erases in page-lengths, which is 256B at a time. To maintain compatibility between the two chips, FlashBridge erases the full 64kB at a time on both the AT45DB and the STM25P chips. It can probably be done faster on the AT45DB implementation than it is right now, but I haven't programmed any of the block erase stuff that the chip actually supports. Another option would be to go in and edit the FlashSettings.h file for the AT45DB and define smaller sector sizes and readjust all those flash parameters, and that should maintain compatibility as well. So let's erase. It takes about 1 second/sector - which is 1 second per erase. $ flashbridge -erase 0 SUCCESS: Sector 0 erase complete And for that AT45DB you'll want to flush after that as well to make sure changes are commmited to flash. Now let's read back address 0x0: $ flashbridge -read 0 0x100 0x0 to 0x100 _________________________________________________ FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF | FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF | FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF | FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF | FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF | FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF | FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF | FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF | FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF | FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF | FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF | FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF | FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF | FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF | FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF | FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF | -----Original Message----- From: Munaretto, Daniel [mailto:[EMAIL PROTECTED] Sent: Tuesday, August 01, 2006 11:46 PM To: [EMAIL PROTECTED] Cc: tinyos-help@Millennium.Berkeley.EDU Subject: for David Moss: [Tinyos-help] Help with real node behaviour!Micaz,tinyos 1.x -----Original Message----- From: Michael Schippling [mailto:[EMAIL PROTECTED] Sent: Tue 8/1/2006 7:19 PM To: Munaretto, Daniel Cc: tinyos-help@Millennium.Berkeley.EDU Subject: Re: [Tinyos-help] Help with real node behaviour!Micaz,tinyos 1.x I haven't used the FLASH so I can't give good advice.
