Can esp32s3 use USB jtag instead of GPIO0 control?

Postby dicethrow » Wed May 29, 2024 2:48 pm

My goal here is to be able to flash my custom PCB, which I have not been able to do yet.

I had thought that I could use USB jtag on the esp32s3 board to get it into 'download mode'.

If I run this python code snippet, implementing the approach in section 33.4.2 of esp32s3 TRM v1.4:

Code: Select all

 
with serial.serial_for_url(args.port, args.baud, do_not_open=True) as serial_instance:
	serial_instance.dtr = False
	serial_instance.rts = False

	serial_instance.rts = False

	serial_instance.dtr = True # set download mode flag
	serial_instance.rts = False # propagate dtr flag

	serial_instance.rts = True 

	serial_instance.dtr = False # reset 
	serial_instance.rts = True # propagate dtr

	serial_instance.rts = False # clear download flag
then the jtag uart terminal displays this: (note, it would otherwise keep displaying the 'invalid header' line continuously)

Code: Select all

invalid header: 0xffffffff
invalid header: 0xffffffff
invalid header: 0xffffffff
invalid header: 0xffffffff

waiting for download
So that is what I was hoping would have the same effect/meaning as doing the GPIO0/reset boot strapping stuff, to make the esp32s3 ready to be reprogrammed. It looks like the TRM uses the phrase 'Joint Download Boot' to describe using GPIO0 during reset to get into a state for reprogramming, which could be relevant here, but it confuses me because above I was able to get the 'waiting for download' to be printed, and yet according to me leaving GPIO floating (and hence being pulled up), I was not in the 'Joint Download Boot' state. I was also able to reprogram esp32s3 devboards using just the above technique fine, without touching GPIO0, but now on my custom PCB this does not appear to work.

However, when I try do program it from this point, I can do a bunch of things, but it always errors out at the same point in commands like this, when I try to flash 'hello world' to it: This output contains some arguments to be more verbose.

TRACE +3.003 Serial data stream stopped: Possible serial noise or corruption.

A fatal error occurred: Serial data stream stopped: Possible serial noise or corruption.
After playing around with making an `esptool.cfg` file with this content, specifically re. the 'custom_reset_sequence' which I believe implements the same thing as my python snippet above. Note the idea for this file came from reading this page: https://docs.espressif.com/projects/esp ... -file.html

Code: Select all

# esptool.cfg file to configure internal settings of esptool
[esptool]
chip_erase_timeout = 140
serial_write_timeout = 8.5
connect_attempts = 7
write_block_attempts = 2
reset_delay = 0.75
# Overriding the default reset sequence to work in an abnormal environment
custom_reset_sequence = D0|R1|W0.5|D1|R0|W0.5|D0
Then, somewhat intermittently, the output looks like this; note there are some of the 'invalid header' lines too:

Code: Select all

But it keeps erroring out. Any ideas? I'm hoping that there is some little change I need to make. Thanks!

Can you post the schematic of your custom PCB?

Ok I think I worked it out. I used the ESP32-S3R8 chip, which I have just realised doesn't have internal flash, and so perhaps the behavior we are seeing makes sense as there is no flash chip in the system - as that's where the error occurs.

Looks like someone else had a similar experience (https://community.platformio.org/t/my-c ... gs/35736/7), so I'll try to copy their fix: order a chip with internal flash (ESP32-S3FN8) and try that on the next build of my custom PCB.

Thanks for the help!

Out of curiosity - is there any way to 'flash' code into the PSRAM of the ESP32-S3R8, without having to use any flash memory?

Technically, this is possible, but we do not have software support for this at the moment.
