Ti nspire hyperterminal problem

[joaospeed100]

While i as installing cas on my nspire the boot2.img got corrupted .

Bought an usb ttl ftdi r323 cable and connetec to the pins 3-rx 4-tx 22-ground

Turn the nspire on pressing doc+enter+2 to flash new boot2 img but on hiperteminal i got a message og random things and the calculator dont stop sending it.

Any help on this???

Hi.

It usually either means :

• the contacts are wrong (short-circuits between adjacent contacts for example)
• the hyperterminal connection wasn't set correctly :
  Baud rate = 115200
  Data = 8 bit
  Parity = none
  Stop = 1 bit
  Flow control = none

Hi thaks for reply

The configuration that i am using is right like your i will check connections tomorrow.

If there happens an short circuit will it screw up the nspire???

Btw it is a ti nspire cx p0711C

Yes, it means the calculator is waiting for the new Boot2 to be sent.

But since you've got no readable messages in Hyperterminal, it still means something is wrong between the calculator and hyperterminal, and that sending the new Boot2 in the current situation probably won't work.

Hi

I just solve the problem from boot2.img corrupted by sending the 4.0 os to the nspire it just install it normaly
