Hello,

I am using a TP2.

I have developped my application using a TL2. It works fine.

I have cut a simcard, and inserted it with a Turbo SIM in my phone. It works.

Now, when I try to program the Turbo SIM on the TP2, I get the following error :
ERROR: Not enough RAM

The SIM card is inserted when I try to program, I get the ATR. I can program the exact same .trb file onto the TL2 but not on the Turbo SIM.

What's happening?

Thanks

The RAM size can depend on device or kernel version.

What does avr-objdump says when you make the app?
E.g. Size PROGMEM: 200 RAM: 0

Can you try to "cemu --reset" the TSIM just to be sure it's not residue of another app?

Hello,

avr-objdump says PROGMEM: 4962 RAM: 174

Here's what I have tried :

cemu --reset
==> OK
cemu --rm-apps
==> OK
cemu --app .../myapp.trb
==> ERR Not enough RAM

I also tried without rm-apps :

cemu --reset
==> OK
cemu --app .../myapp.trb
==> ERR Not enough RAM

btldr -s -i says
Unsupported or locked

I tried to "unlock" the card with cemu using the "TPIN" printed on the label that came with the card, but it says "wrong pin" (unlock answer 9804).
I assumed the TPIN printed is in fact the PUK of the TPIN, so I used --pin 0000 -puk [printed on label], but it said "unblock failed: wrong puk" (unblock answer 9804)

I did only one try of the above commands so as not to block the card.

I am lost here: what is the TPIN printed on the label with the card? How do I use it? Is my card really locked?

What should I do next? Thanks

RAM 174 bytes for clean device shouldn't be problem.

TPIN does the same as --reset, it can be used from phone itself, i.e. when turning on the phone enter this TPIN, phone says error, then enter proper SIM PIN.

But cemu --reset should do. If not then the last/best option would be to reflash the TSIM kernel with btldr. What exactly means "unsupported or locked"? Can you post some dump or screenshot?

Btw. what does "cemu --info" say?

What turbo-prog-utils package/version do you use?
Seems like kernel version vs. turbo-prog-utils version issue.

Bootloader cannot be reflashed. Latest/whatever kernel we usually send by email.

Btw. what kernel version is the TL2? Please post cemu --info.

Now I don't get it at all, it also stopped working on the TL2.
It's like there is a memory leak.

Is it possible that I am not disallocating the EEPROM memory correctly in my app?
Won't a --reset also reset the EEPROM memory?

Is there something I can check on the .trb file?

I have tried reflashing the TL2 with btldr, and I still cannot program it. It's like the .trb file is corrupted somehow.

Any help will be very much appreciated.

By refactoring my application, I was able to reduce the memory usage to 96 bytes.
Now the problem is gone. Looks like 176 was too much RAM.

How much RAM is available for the application ? The ATm128 microcontroller has 4Kbytes RAM

Thanks !
