I actually ran into this issue, too, with Google’s code lab and Sparkfuns. I’ve been able to install the pre-compiled examples, but nothing custom.

This failed me from two different computers with two different Edge boards. I’m running on Arch Linux on both machines. The only other commonality between these setups is that I’m using the same FTDI board.

Additionally, following the instructions here yield the same result: https://codelabs.developers.google.com/codelabs/sparkfun-tensorflow/#5

According to the troubleshooting section on the next page of the codelabs instructions, this is happening because I need to follow the «hold down the button marked 14 while running the script. Hold down button 14, hit the RST button, then run the script, while holding the button marked 14 the whole time.»

Just to confirm: this is exactly what I’m doing.

@PaulTR there are no pre-compiled examples. The script tries to install bin/main_nonsecure_wire.bin on the device, and that is where this is failing. That file doesn’t exist in the repository unless you build it using make bootload.

Hi @karma0, @PaulTR,

@karma0 — since you’re using a unix-like OS I wanted to double check that you’ve seen this: https://stackoverflow.com/questions/55463159/sparkfun-edge-bootloader-problems

Additionally I have found that if the executing code has a lot of serial communication that it can cause the bootloader to miss the initial reset request. To avoid this problem my upload sequence is:

press and hold button 14
press and release reset
start the uploader script (automatically toggles reset again)
let go of button 14
press reset again (gets the board into application mode)

Here’s a simplified makefile that I wrote to simply upload a bin, and avoid any compilation (requires a binary file to upload)

SDKPATH	=# note: you need to fill this absolute path out for your system. 
BOARDPATH = ${SDKPATH}/boards/SparkFun_Edge_BSP#if this doesn't match your system please modify it
COM_PORT =#this too
BAUD_RATE = 921600#note: 921600 for Edge boards from SparkFun, 115200 for Edge boards received at the TensorFlow dev summit

BINUPLOADTARGET=SparkFun_Edge_Project_Template.bin

all: binupload
binupload:
	${SDKPATH}/tools/apollo3_scripts/create_cust_image_blob.py --bin $(BINUPLOADTARGET) --load-address 0xC000 --magic-num 0xCB -o main_nonsecure_ota --version 0x0
	${SDKPATH}/tools/apollo3_scripts/create_cust_wireupdate_blob.py --load-address 0x20000 --bin main_nonsecure_ota.bin -i 6 -o main_nonsecure_wire --options 0x1
	${BOARDPATH}/bsp/tools/uart_wired_update_sparkfun.py -b 921600 $(COM_PORT) -r 1 -f main_nonsecure_wire.bin -i 6

And here’s a binary to try with it:
SparkFun Edge Project Template Binary

Please let me know how this turns out for you — we’d like to be able to solve this problem for everyone else too. And thank you a lot for taking the time to report this to us!

I had the same problem and changed the Makefile to correct the baud rate that is by default 115200 but is set too high at 921600 in the Makefile:

../../../bsp/tools/uart_wired_update_sparkfun.py -b 921600  $(SERIAL_PORT) -r 1 -f $(CONFIG)/main_nonsecure_wire.bin -i 6

to:

../../../bsp/tools/uart_wired_update_sparkfun.py -b 115200  $(SERIAL_PORT) -r 1 -f $(CONFIG)/main_nonsecure_wire.bin -i 6

Thanks for the help! Here’s the output, seems identical:

@genivia-inc thanks for the feedback. That is also something that I’ve tried. Running uart_wired_update_sparkfun.py by hand and passing the correct baud rate yields the 48 bytes response (and occasionally 11 bytes) no matter which bin file I try.

I just ran that modified makefile to get some example output that you can target… I notice that after ‘Sending Hello’ I get ‘Received Response’ and ‘length = 0x58’ where in your output we’re seeing ‘received bytes 48’

That mismatch in length makes me think that the UART communication is off — either by using the incorrect baud setting ( but you’ve tried both 115200 and 921600 if I recall correctly ) or the USB-serial bridge is misbehaving (possibly due to the same kind of driver issues as in the Stack Overflow post?).

Can you verify the accuracy of your UART output from the FTDI converter?

(p.s. the above makefile text is in MakeUpload.mk in the same directory as SparkFun_Edge_Project_Template.bin)

FIXED!

Following the suspicion that there may be driver issues with Arch Linux, I was able to find some other people having similar issues with the Linux kernel built-in drivers with various knock-off Arduinos coming from China. That eventually led me to this project that overrides the Linux ch34x drivers and based on the vendor’s drivers (which doesn’t compile against kernels beyond 3.13.x … Arch is currently at 5.0.7!!)

That being said, if you are getting the 48 bytes response, it’s probably safe to say that the ch341 drivers are outdated and you need to find an alternative for your platform/distribution.

Thanks for the help! I’ll leave it up to you if you want to close out this issue or leave it open for others to post their solutions.

Thanks karma0! This will be very helpful for many folks.

All, just got my new SparkFun Edge, trying to build and flash test program, build is OK, but flashing failed.

I’m using Ubuntu 19.10. I’ve followed this link https://learn.sparkfun.com/tutorials/how-to-install-ch340-drivers/all#linux

So CH341 driver issue is not a problem, after plugin the USB serial to my PC, dmesg shows:

[66495.174916] usb 1-1.2: new full-speed USB device number 23 using ehci-pci

During TLS handshake, client machine makes a request to IIS server by sending Client Hello package. Then the server responds it with Server Hello.

If the server is not sending Server Hello package, the communication won’t be established and the customer is likely to see error messages below:

Internet Explorer:

This page can’t be displayed
Turn on TLS 1.0, TLS 1.1, and TLS 1.2 in Advanced settings and try connecting to again

Chrome:

This site can’t provide a secure connection
The website sent an invalid response
ERR_SSL_PROTOCOL_ERROR

Solution

Keep in mind that the TLS protocol errors above might be misleading. However, you should start the troubleshooting by analyzing TLS negotiation first.

Here are the steps to go through:

Make sure the website binding in IIS for 443 port has a certificate attached
Make sure all TLS versions are enabled in Internet Explorer (This is for testing. You can later disable the unsecure versions)
Check SCHANNEL registry keys to make sure what you set in Internet Explorer is applied at registry level
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSecurityProvidersSCHANNELProtocols
Collect a network trace. Check if the client and server are agreeing on a cipher suite. If they are not, make sure the client’s cipher suite list matches with the server’s list. Related Group Policy setting:
Computer Configuration > Administrative Templates > Network > SSL Configuration Settings > SSL Cipher Suite Order
If the issue sill exists, look for any network device (proxy, firewall, load balancer etc.) in between that might be intercepting or blocking TLS traffic

If you don’t see any issue with TLS protocol and network devices, continue the troubleshooting by focusing on the web server:

Check the website binding in IIS. The certificate should be valid
Make sure the port 443 is being listened (netstat -an -p TCP | find /I «listening»)
Change the port number to 444 and test. If it is accessible, it means there is a software blocking 443 port
Disable Windows Firewall (If it works, you can enable it back and set up rules accordingly)
Look for any third-party applications in the server such as Symantec Endpoint Security and Symantec Data Center Security Server Agent (Security Server Agent uses port 443). Uninstall them (Don’t just disable them. Uninstall them completely. If it works, you can install them back and configure them accordingly)
Check if there is any Microsoft software that is using port 443. Applications like SQL Server Reporting Services (SSRS) and Windows Admin Center might interfere the port 443.

Пробовал подсовывать лоадеры из сети, все равно авторизацию просит. Раньше вроде работало.

Всем привет! Вопрос к тем у кого есть данный девайс. Подскажите, есть ли там в софте нечто подобное eMMC File Manager от z3x?

Есть. С небольшими различиями. Но функционал тот же.

Hello, I am new to this arduino stuff. I’m doing a school project that requires a wifi module (Nodemcu Esp8266). The code has been compiled and i have a problem flashing it to Esp8266. It keeps saying «Error: failed sending 0xC0» and «Error: espcomm_upload_mem failed».

I tried changing to different usb cables, shorting the ground and D3 and pressing the flash and reset button but still it wouldnt work. The Led on my Esp8266 also does not blinks when it plugged in to the pc, maybe i do not know how to put the Esp8266 into flashing mode.

Really appreciated if you could help me!
