I just received a UV380 from here :
https://www.ebay.com/itm/264446265553
it's the GPS version, and works perfect;y with OpendGD77.
S/N: 2205L01293
It might be old stock since it came from NY.
73's

I took a chance and ordered one and received it today Feb 17 which worked as well after loading Opengd77. Serial number was 2205xxx. eBay shows there are 10 left, 130 sold. No guarantee that the remaining 10 are "old stock", but the seller does take returns if you pay return shipping.

Colin and I have made some progress with understanding why the firmware will not run on the new radios

The CPU in this radio does not seem to have the same number of Interrupt priorities as a genuine STM32F407 CPU.

It seems to only have 8 levels of interrupt, not 16, and the operating sustem FreeRTOS checks how many interrupt levels are available and if its not 16 it simply halts

Because I don't have one of these new radios, I have been sending test versions to VE2NCK, and we think it may be possible to build a version of the firmware which only uses 8 interupt priority levels.

However at the moment we don't know whether there are any side effects of using a reduce number of priorities.

i.e The firmware is now booting up on the new radios, but we don't know whether it works correctly.


Colin deserves extra thanks, because he has bought a new RT3S just debug the problem, even though he already has several other RT3S and UV380 radios.

Both of you deserve a lot of credits for the awesome work involved in creating, porting and debugging such an piece of art.
i'm glad i had a chance to learn from you and be a tool to enable this debugging
thanks to both Colin and Roger for there patience in dealing with my novice questions and the time you devoted to this projet

Excellent and outstanding work and both deserve 100% And Well Pat on the back and Handshakes.

Once Tested Firmware Is out ready to be tested I sure do sone tests.

Anyone with one of the new radios which did not work with the firmware, please can you try this version


downloads/MDUV380/Firmware/5ed1bcc0433f ... DUV380.bin


This version should also work OK on the old radios with the genuine CPU chip

Many Thanks Yes I Can confirm I’ve just uploaded this Firmware on my New Clone Chip and it Flashed and install 100%

Tested DMR Simplex and on a Repeater. Works 100% Also didn't need to hold hold # To Hear the Repeater like I had to previously

Now testing time. Thanks Again

OK.

Thanks

Several people have been testing the firmware on both old and new radios and it appears to be stable. However I will not put it into the Latest folder until more people have had chance to test it on both the original radios with genuine CPU's and these new radios with clone/fake STM32 CPUs

Com a ajuda de PU2PWR (a quem agradeço imensamente por sua paciência e disponibilidade), comunico a todos que esta firmware funcionou corretamente no meu Tyt md uv380. TKS VK3KYY e a todos que exaustivamente se dedicaram neste mod. 73/51

This version is suitable for retevis rt3s with GPS? Or there is no difference with or without GPS?
