DSATX & Brainstem firmware upgrade failure?

Postby Kosti » Wed Oct 15, 2008 5:05 am

Hi All,

I finally bench tested everything and wanted to update the firmware to 114.

Connected the serial brainstem and DSATX, selected comport and baud rate 115K, reset pins, update failed.

Tried again, failed again, this time at a different page#, tried again, failed.

Updated megaload to ver7, tried again, fails immediately.

Hooked up hyperterm @ 9600 baud, typed E y D y, tried to query using GXX, nothing no response!

reset powered down, connected to PC, seems the DSATX has no firmware now, power LED doesn't light up and motherboard doesn't boot with DSATX.

I need a fix as car is getting picked up in 2 days for finally testing with AMPS and now it seems my DSATX is stuffed.

So sad and mad at the same time!

Has this killed my DSATX?

Went out and bought a USB FTDI TTL 5 V cable, wired it up as per mpegbox forums sticky and it doesn't work at all when using hyperterminal.

Hyperterminal shows up some weird results when pressing say "E"
using the brainstem EG:

Enable Writing? y/n…E
Enable Writing? y/n
Enable Writing? y/·E
Enable Writing? y/E
Enable Writing? y/E
Enable Writing?*yE
Enable Writing? E
Enable Writi®öE
Enable Writé·E
Enable WritiE
Enable WritE
Enable Wr©ºE
Enable WrÚE
Enable WE
Enable]

I get nothing in Hyperterm when using the USB FTDI cable

The LED on the DSATX is always off, even after placing a jumper on B1:B2

Led used to come on when psu was working.

Need a quick fix pls
