Croduino NOVA programs stop running after reset or power cycle

Customer:

I recently got a Croduino NOVA board and set up the Arduino IDE according to your web instructions. I tested it with the blink example from your site. The program uploaded successfully and runs correctly (the LED blinks at the set interval), but after pressing the reset button or power cycling the board, the program stops working.

I tested this with other examples provided through the IDE interface as well (for example, WiFiAccessPoint), and the same thing happens every time.

What else could I try to determine whether the problem is in the IDE/compiler, the programs themselves, or the Croduino board?

Also, is it normal that uploading programs to the NOVA takes a very long time (much longer than on a regular Croduino), even for short programs like blink? It seems like it reprograms the microcontroller from scratch every time.

Original message (Croatian)

Kako sam napokon nasao malo vremena “poigrati” se sa nedavno kupljenom

Croduino-NOVA plocicom, naletio sam na problem za koji nisam uspio

ustanoviti da li je uzrok u mojim postavkama (Arduino IDE) ili mozda

nesto nije u redu sa samim Croduinom.

IDE je podesen prema vasim uputama na webu te je za prvi test iskoristem

“blink” primjer dan na istoj stranici. Program uredno uploadan i radi

(ledica blinka u danom intervalu) no nakon pritiska reset tipke i/ili

prekida napajanja (power cycle) program vise ne radi.

Probano je i sa drugim primjerima koji su dani kroz IDE sucelje (npr.

WiFiAccessPoint), te se ponavlja ista stvar.

Sta bi se jos moglo probati kako bi se ustanovilo je li problem u

IDE/compiler, samim programima, ili Croduino plocici?

Zahvaljujem na odgovoru.

p.s.

Da li je normalno da upload programa na NOVU traje dugo (puno duze nego

kod klasicnog Croduina), cak i tako kratke programe kao sto je “blink”?

Izgleda kao da svaki put reprogramira mikrokontroler “od nule”?

Soldered Support:

If you purchased the board when it was first released, you may have the following issue (fortunately easy to fix). You need to cut one trace on the PCB with a knife or scalpel for everything to work properly. I’m sending you an image so you can see which trace it is. After cutting it, you should no longer have this problem.

Regarding the upload duration: yes, it takes quite a while because the library that Arduino provides for the ESP is quite large. Whether you upload just a simple blink or a complex script, the entire library is uploaded to the board. When you click Compile or Upload, the size of the code is displayed at the end of the process. You’ll see that with the NOVA it’s over 250kB, while with a regular Croduino a simple blink is only a few kB. The upload speed on the NOVA itself is quite fast, but it still takes time. There’s no solution to this problem except using a faster chip for USB communication.

isprike na problemu, za početak :slight_smile: Ako ste pločicu kupili odmah čim smo je predstavili, moguće je da imate sljedeći problem(srećom lako popravljiv). Jedan vod na tiskanoj pločici trebate prerezati nožićem ili skalpelom da bi sve radilo okej. Šaljem Vam sliku u prilogu da biste vidjeli o kojemu točno se radi. Nakon što ga prerežete, ne biste trebali više imati ovakav problem :slight_smile:
Što se tiče dužine uploada, da, traje dosta dulje, budući da je sam “library” koju omogućava Arduino na ESPu poprilično velik.. Bez obzira uploadali samo običan blink ili neku kompleksnu skriptu, cijeli library se uplada na pločicu, a to traje.. Kada stisnete Compile ili Upload, na kraju procesa Vam se ispisuje veličina samog koda.. Vidite da je s NOVOm to više od 250kB, dok s običnim Croduinom iznosi(za običan blink) tek nekoliko kB. Na samu NOVU je brzina uploada dosta brža, ali opet to ipak traje.. Nema rješenja ovome problemu osim koristiti brži chip za USB komunikaciju :slight_smile:
Usput, dodao sam Vaš email da dobijete email kada nove Croduino NOVA pločice budu spremne(bez potrebe za rezanjem ovog voda) kako bismo Vam zamijenili ovu zarezanu .. ako Vam to nešto bude značilo.
Sretan Uskrs!
