Failed to read firmware version after 6 attempts

[M0XZT]

Mmdvmhost fails to read firmware version after updating mmdvm_hs_dual_hat(DF2ET) to 1.3.5

Do the LEDs blink at startup?

[M0XZT]

No, just the power LED, rolled back to 1.3.3 and it's working ok

[juribeparada]

Uhmmm, bad thing, probably we are running out of RAM for duplex mode

[juribeparada]

I will fix reducing ring buffers again soon in the next release :(

[juribeparada]

OK, it should be fix now in v1.3.6. I deleted v1.3.5

[M0XZT]

Working fine now. Thanks Andy

I can probably free up a little RAM that's allocated to the UART Serial in the Arduino Core

But its not going to be much.

I think the RX buffers allocated to each hardware serial channel are 64 bytes.

I think you may be using one UART Serial for the Raspberry PI version, but the other 2 could be removed and free up 128bytes

There is probably other stuff in the core that could be taking RAM that you don't need, but someone would need to look in the map file to see what could be released

Thank you Roger, but that is not so much, specially for the amount that I tried first time (the same amount that works OK for G4KLX MMDVM firmware). Now it is solved, I reduced a little more, but its still an improvement compared to v1.3.3. This ring buffer increment is only to reduce some modem NAK warnings (buffer overflow) that is produced for long network delays (too many DMR silence fills for example), then it is not so critical. Anyway, this affected only duplex devices, because firmware needed more resources.

[rogerclarkmelbourne]

OK.

Bonjour à tous Mmdvmhost ne parvient pas à lire la version 1.3.6 ou 1.3.7 du micrologiciel après la mise à jour mmdvm_hs_dual de EA7GIB merci

Hello, have you tried to compile latest source code with "make" method using a Raspberry Pi or a computer with Linux, with latest arm gcc tools?

Hello thanks for the answer it works updated in 1.3.7 thanks
