flash read err, 1000 on ESP32-WROVER

[hopkinskong]

Hi,

I am using ESP32-WROVER module, for some reason, it suddenly stopped working. When on manual reset:

Code: Select all

$ make monitor

And it goes on forever.

When I try to flash:

Code: Select all

$ make flash

A fatal error occurred: Timed out waiting for packet header
make: *** [/home/xxx/esp/esp-idf/components/esptool_py/Makefile.projbuild:55: flash] Error 2

It seems that the ESP32 does not recognize the flash chip anymore. Is there any solution, or I need to replace the whole module?

BTW,
BOTH Secure boot in bootloader and flash encryption in boot are off in menuconfig;
Flash SPI mode is DIO in menuconfig

Thanks.

Solved.

I recommend anyone encountering the same issue check:

1. GPIO12 (MTDI) must be pulled up to power SDIO with 1.8V, it is already done internally in ESP32-WROVER. However if your board is pulling down that pin, it will power the internal SDIO LDO with 3.3V which will damage the PSRAM/SPI FLASH. Luckily my board left that pin floating.

2. This is my issue: Pin 20 (CLK) and Pin 21 (SD0) shorted, that makes SPI flash is not working, luckily it isn't shorted to the 3V3 rail, or I am really need to replace the module.

hii all,

i am also facing this similar problem. exactly what are the reason for esp flash getting corrupted ?.

[Kiranoday]

I am also facing the same issue...

[hugonbs]

I'm experiencing the same issue, but only some times when the module are recovering from deep sleep (the average is +/- 1/30000)

Hi,I have the same problem... What I have bad?

flash read err, 1000
ets_main.c 371

I tried put resistor 5K to GND on IO2 but same
Not let flashing...
I used a normal USB/TTL wire

Hi cvargcal,

The line "Warning: Could not auto-detect Flash size (FlashID=0xffffff, SizeID=0xff), defaulting to 4MB" indicates that communication with the SPI flash chip inside the WROOM32 is failing.

It looks like you have external peripherals connected to a number of the SPI flash bus lines. GPIOs 6-11 should not be used for any other purpose, unless you're very careful about coexisting with the SPI flash chip. Check ESP32-WROOM32 datasheet section 4 for more details.

Thanks you for your answer.... I saw the PIN20 (CLK) i used for ADC... so I did cut the wire and now show this

But still no let write the software...


Edit

I see... I can not use that pins... so the UART1 can not used?
I cut all wires to 6-11 and now show this

You can use the GPIO Matrix to remap UART1 to any other GPIOs which are unused.

I cut all wires to 6-11 and now show this

Looks like it's mostly working?

thanks , now work fine and let me flashing... but its rare.. I have presed reset and boot sw for can flashing... Well I have fixed my PCB .
