It’s not you, it’s the crappy counterfeit FTDI chip in your USB to serial adapter. AdapterVccDTRRTSTXRXA5.103.443.441.661.49B5.100.003.533.530.00C5.093.323.323.322.43D5.113.463.463.462.14E5.103.373.373.373.28F5.093.373.373.373.53G5.102.253.413.413.15H5.113.703.703.703.63Test SetupHere are the perfboards I built to program the modules:Version 0Only works with the 4D Systems uUSB-PA5 Adapter. Two other programming circuits on board require manual reset/mode selection and do not work.Version 1Version 2Improved upon Version 1, by making a common header layout for programming: 5V (red), GND (green), DTR (yellow), RTS (blue), TX (orange), RX (gray).The trace wires are shorter and more uniform this way, and there’s less chance of screwing up the adaptation wiring.

Also, the adapters all become interchangeable, which improves test consistency.Test ScriptI’ve created a test script to test each USB adapter, using a variety of baud rates. The code is.FTDI FT232RQ (4D Systems uUSB-PA5 Adapter)Works.FTDI FT232RL (Chinese counterfeit)Does not work.Markings on the board call it a YP-05. You can get these for about 3 EUR on eBay, and they work reasonably well as plain USB serial adapters. But they always fail for me while programming the esp8266, with the following errors:$./esptool.py writeflash 0x00000 x.binConnecting.Erasing flash.Took 2.21s to erase flash blockWriting at 0x00008000. Thanks for you study. You have revived my hope.

My error doesn’t seem to show up in your testing, however. I have spent way too many hours trying to figure this out. I have a black ESP-01 and a Silicon Labs CP2102 (black PCB, from eBay). I tried the CP2102 (black) after having lot of problems with the FTDI (i have now a nice collection and only 1 of them works with the ESP modules).This CP2102 doesn’t work at all.Same error than the FTDI: invalid packetMEMORY STARTELSE. 26Invalid head of packet (”)Exception in thread Thread-6:Traceback (most recent call last):File “threading.pyo”, line 801, in bootstrapinnerFile “downloadpanelinfo.pyo”, line 785, in runFile “esptoolapi.pyo”, line 763, in flashdownloadthreadFile “esptoolapi.pyo”, line 1761, in initFile “esptoolapi.pyo”, line 1646, in readpacketException: Invalid head of packet (”)I guess the problems are the serial modules, with counterfeit, mal functioning circuits or bad design, because when I use the good FTDI no problem at all. Are these legitimate FTDI cables, like? If not, then there’s no guarantee here.

Only the legitimate FTDI cable, or one of the adapter boards with a legit FTDI chip, worked as the gold standard for me.But I’m surprised the CP210x chips aren’t working for you, as I had pretty good luck with them. Perhaps someone’s built a cheap counterfeit, or like you mention, maybe there’s a new version of the PCB, which has some kind of design flaw. Only thing to do in this case is to probably just buy other models and see if they work, unfortunately. Alo.All the FTDI and CP2102 are from eBay.The only FTDI (also from ebay) that works, was bought years ago.It looks the FTDI modules are getting worse over the time, because I have a chronology of them and they present more problems until a recent one was a counterfeit part (driver showing “not genuine”). Then I moved to the CP2102 (well I try xDD).

I don’t need to program at high speeds just programming is enough.The point with the FTDI is they work fine with 115k in AT mode (even high rates) but they don’t when programing. I also realised recently the some modules corrupt data: I was testing a personal project sending data at 115k but with a very high rate (dozen of ms as much) and then I realised some data, randomly, was corrupted (“then” was about 1 week of headaches because software logic was perfect, so, why the results are wrong?!).

So the problem looks related to the speed and the rate of transmission. Buffer corruption? Dunno.About the CP2102 I thought it could be a counterfeit or some problem with the PCB but I don’t have tools to check this. The tools from the official manufacturer work, but I noticed that if you try to change the assigned serial com in the module, it never gets the number you wants. Download latest tina 9.3.50.47 keygen - free download torrent 2017 with crack. It says it was programmed but when enumerating Windows assigns one different. Not sure if it’s normal or not. Without proper tools it’s hard to check anything.Visual inspection reports the module shown in your site and mine has only a visible difference: the PPTC.

Mine has a 000 resistor instead. It shouldn’t be a problem but if you find a difference here, there can be more hidden. Hello, I use Prolific PL2303HX for ESP-01. It works to run AT commands from terminal but it didn’t work when I tried esptool.py command just to check flshid, chipid, etc. Do you have any idea about the problem?My terminal configuration use baud 115200 at COM7.
