Protocol Handshake with system_upgrade_start()

[AgentSmithers]

For anyone who has gotten this to work, My understanding is that the framework supports HTTP firmware upgrade natively without having to do SPI WRITE/ERASE logic on our own, I may be missing a serverside requirement but I wanted to confirm with everyone here that I can go this route with NONOS sdk.

Code: Select all

static void ICACHE_FLASH_ATTR ota_finished_callback(void *arg)
{
   struct upgrade_server_info *update = arg;
   if (update->upgrade_flag == true)
   {
   os_printf("[OTA]success; rebooting!\n");
   system_upgrade_reboot();
   }
   else
   {
   os_printf("[OTA]failed!\n");
   }

   os_free(update->pespconn);
   os_free(update->url);
   os_free(update);
}

static void ICACHE_FLASH_ATTR handleUpgrade(uint8_t serverVersion, ip_addr_t * server_ip, uint16_t port, const char *path)
{
   const char* file;
   uint8_t userBin = system_upgrade_userbin_check();
   switch (userBin)
   {
      case UPGRADE_FW_BIN1: file = "user2.bin"; break;
      case UPGRADE_FW_BIN2: file = "user1.bin"; break;
      default:
         os_printf("[OTA]Invalid userbin number!\n");
      return;
   }

   uint16_t version=1;
   if (serverVersion <= version)
   {
      os_printf("[OTA]No update. Server version:%d, local version %d\n", serverVersion, version);
      return;
   }

   os_printf("[OTA]Upgrade available version: %d\n", serverVersion);

   struct upgrade_server_info* update = (struct upgrade_server_info *)os_zalloc(sizeof(struct upgrade_server_info));
   update->pespconn = (struct espconn *)os_zalloc(sizeof(struct espconn));

   os_memcpy(update->ip, server_ip, 4);
   update->port = port;

   os_printf("[OTA]Server "IPSTR":%d. Path: %s%s\n", IP2STR(update->ip), update->port, path, file);

   update->check_cb = ota_finished_callback;
   update->check_times = 10000;
   update->url = (uint8 *)os_zalloc(512);

   os_sprintf((char*)update->url,"GET %s%s HTTP/1.1\r\n""Host: "IPSTR":%d\r\n""Connection: close\r\n""\r\n", path, file, IP2STR(update->ip), update->port);

   if (system_upgrade_start(update) == false)
   {
      os_printf("[OTA]Could not start upgrade\n");

      os_free(update->pespconn);
      os_free(update->url);
      os_free(update);
   }
   else
   {
      os_printf("[OTA]Upgrading...\n");
   }
}

ip_addr_t test_ip;
IP4_ADDR(&test_ip, 255,255,255,255);
handleUpgrade(2, &test_ip, 80, "/");

It seems not be a valid bin according to the length 76, maybe you should check the url first.

I spotted that too. Testing the URL I got this. Maybe the next step is setting up a LAN server and wiresharking it.

Okay, The issue I had was that my host is on "Shared" hosting so I had to put my Hostname in the HTTP GET request directly instead of the IP:PORT as the "HOST:" entry. Once I did that It found the length of the actual Bin file.

Now at this point, I think it's trying to do a 2nd get request and is unable to get to the actual bin file. If I am correct is there a way to override the "GET" request the firmware is making when reaching out for the new .BIN file? am I in the right direction?


UPDATE: I also found this, I am unsure it is related. Is there something in the .BIN file that will identify the Bin file it is 1 vs. 2?
https://stackoverflow.com/questions/471 ... e-bin-file

Attached is a PCAP capture I did on a local webserver showing the same result. I think something is up with the firmware somehow, But I've tested the .BIN in my own custom FOTA and it works fine, Now that I am using the Built in HTTP method I am having the issue with the same verified FOTA .BIN file.

Update: I may be hitting a 10second timeout?

Post Script: Does this work at all with Custom Firmware? Or is this function only for AT+ firmware?
