@petrynchyn I see some problems in the areas that are allocated for the ROMS and the actual location where they are downloaded. Can you check with

make clean
make 
make flashinit
make flash
make flashconfig

And see if it works for you. The last command make flashconfig takes care to reset the rboot configuration so that a correct one will be generated on the next boot.

petrynchyn · 2018-11-26T06:12:35Z

@slaff result is similar, I will try later on another ESP module

etmmahi · 2018-11-26T08:49:58Z

Unfortunately I see the Basic_rBoot OTA also failing, even with the make flashconfig

petrynchyn · 2018-11-26T10:14:57Z

Problems begin at the stage of establishing a connection with WiFi. I can connect to WiFi only after flash sample Basic_WiFi and after connecting with WiFi i flash Basic_rBoot

wdt reset

Also interested in this, any update?

Evgsurf · 2019-02-07T11:38:03Z

I have the same problem with Basic_rBoot.

before I used "make flashinit" system was able to connect to WiFi, but did not download and update on "ota" commans (it just out "Updating...." send request to rom0.bin and nothing more (did not hungs, just nothing more))

now I have the same situation like wrote another guys ...

P.S. I can restore system for WiFi by flashing another sample (HttpServer_WebSocket for exapmle) and flash again rBoot and system gets ip, but Updating does not work :(

andr2000 · 2019-02-07T12:37:39Z

I traced it down to spi_flash_erase_sector which hangs and makes the WDT fire.
I also tried to erase the same sector that OTA wants right before enabling WiFi and it works ok...
My 12E module was externally powered with 2A power supply, so not sure if power is an issue here.
flash{init|config}, erasing, writing all 4MiB with 0xff didn't help either.
@anakod @raburton do you by chance have any inputs on this?
The issue is open since Nov 2018 and we still suffer from this....

etmmahi · 2019-02-07T15:58:07Z

Hi, I have already traced it down to the rboot library. The issue is that during the update of the flash sectors (erase or write) the interrupts (except flash interrupt) should be disabled. Maybe the faulty ISR do not have ICACHE_RAM_ATTR set and will crash because the flash is not accessible.

Updates to the file rboot-api.c (actually the patch files must be updated)

somewhere in the top of he file add:

#define FLASH_INT_MASK ((1 << ETS_SDIO_INUM) | (1 << ETS_GPIO_INUM) | (1 << ETS_UART_INUM) | (1 << ETS_FRC_TIMER1_INUM))

around line 70:

	spi_flash_read(BOOT_CONFIG_SECTOR * SECTOR_SIZE, (uint32*)((void*)buffer), SECTOR_SIZE);
	memcpy(buffer, conf, sizeof(rboot_config));
	ets_isr_mask(FLASH_INT_MASK);
	spi_flash_erase_sector(BOOT_CONFIG_SECTOR);
	spi_flash_write(BOOT_CONFIG_SECTOR * SECTOR_SIZE, (uint32*)((void*)buffer), SECTOR_SIZE);
	ets_isr_unmask(FLASH_INT_MASK);

in begin of function rboot_write_flash add:

	SpiFlashOpResult fop;

around line 160:

		// erase any additional sectors needed by this chunk
		lastsect = ((status->start_addr + len) - 1) / SECTOR_SIZE;
		while (lastsect > status->last_sector_erased) {
			status->last_sector_erased++;
			ets_isr_mask(FLASH_INT_MASK);
			spi_flash_erase_sector(status->last_sector_erased);
			ets_isr_unmask(FLASH_INT_MASK);
		}

		// write current chunk
		//os_printf("write addr: 0x%08x, len: 0x%04x\r\n", status->start_addr, len);
		ets_isr_mask(FLASH_INT_MASK);
		fop = spi_flash_write(status->start_addr, (uint32 *)((void*)buffer), len);
		ets_isr_unmask(FLASH_INT_MASK);
		if (fop == SPI_FLASH_RESULT_OK) {

I have tested this and it makes my OTA rock solid.

@petrynchyn @andr2000 @Ph3r0x @Evgsurf Guys, can you check the suggested change and report if it is working for you?

petrynchyn · 2019-02-08T13:36:15Z

OTA seems to work, but problem remained with connection WiFi after make flashinit (SDK 3)

andr2000 · 2019-02-08T17:38:50Z

I can confirm what @petrynchyn says. OTA does work, but WiFi is still an issue.
Frankly, I am not surprised, as we workaround interrupts during OTA, but still WifiStation class wants to
write its settings to flash (auto-reconnect and credentials):

-                       WifiStation.config(CONFIG_WIFI_SSID, CONFIG_WIFI_PWD);
+                       WifiStation.config(CONFIG_WIFI_SSID, CONFIG_WIFI_PWD, false, false);

With the change above I effectively disable wifi_set_opmode and wifi_station_set_config both willing to write to flash (if I understood the SDK documentation correctly).
And this is at least, but not at last. As per my understanding any flash write/erase may cause an issue if interrupts are enabled. So, I would consider the above patch from @etmmahi (who did a really good job!!!) to be just a particular workaround and in order to fix the issue we do need understanding what is the real root cause for this.
IMO, it is likely as @etmmahi said, that interrupt handlers should be examined if they still reside in RAM, because flash erase/write effectively unmaps QSPI from the CPU which may lead to hang and WDT reset...

andr2000 · 2019-02-08T20:20:29Z

guys at Arduino finally managed to "Remove interrupt disable around flash operations"

"All interrupt service routines are supposed to be in IRAM now, so there
is no need to keep interrupts disabled while doing flash operations.
Remove the IRQ disable/enable from the ESP.flash* methods."

So, indeed, there is something trying to run from flash in some interrupt handler....
