Bricked FRDM boards , Fourth phase

chop — Sun, 30 Jun 2013 13:17:09 GMT

Well , my 4 boards went back to Freescale in the States four months ago for checking , nothing heard as to what was wrong or whatever , So...... having heard about the ability to use the FRDM board with mbed I thought I'd give it a try as I now have a new PC with a fresh XP installation and thought surely nothing can go wrong , $9 later Element 14 delivered a new board , Plugged into the PC demo program runs as "on the lable"

PEMicro/Freescale - CDC Serial port message appears and unit enumerates as FRDM-KL25Z (F:) so far so good ! , checking contents shows blank ( not so good) properties , 0 free space, 0 used space , 0 capacity

Try repowering FRDM , and it comes up as BOOTLOADER(F:) but with a windows warning "Windows - Delayed Write Failed" and no green LED ( but demo program still running well)

Repower again and it shows as INVALID(F:)

So now I seem to have yet another bricked board , I beginning to feel that Freescale has a personal vendetta :-) , I have TI 430 Launchpads (2) , TI stellaris launchpads (2) an STM32F4 discovery , various Arduinos, PICs etc , never had a problem with any of them, despite some fairly rough usage I use Freescale BDM programmed 8 bit and 16 bit processors in several products with no problems at all !!

Is it just me or are these boards so very touchy ? five out of five failures seems to defy logic

Final posting :-

Zahar Raskin emailed a new bootloader installer ...... All AOK , board now operates as expected , Under both XP and Linux , even set it up on MBED , so it's all systems go and many thanks to Zahar

Just a pity I sent the previous boards back to Freescale when the solution was so simple :-)
