I noticed when I Repeatedly run large programs - with long Printed Text,
- that the Shell Que runs Slower and takes Longer to Start each time : 10 mins .. 30 mins .. 60 mins .. ?
I also notice Thonny on TaskManager increases Size (without Decreasing) each time :
- 1M .. 1.5M .. 2M .. 3M
Until I completely restart Thonny.
This seems like a clear Memory Leak - for the Shell Que !
Esp32-P4 on Wt9932P4-Tiny board.
- Can Not get Micropython installed to work.
- just returns Header errors
Trying to install some version on Micropython Bin on the board.
Internet states that it is workable using Esp32P4 Standard bin.
Does Not Work !
What bin are we supposed to install on it ?
invalid header: 0x5b98cbd8
invalid header: 0x5b98cbd8
PROBLEM IN THONNY'S BACK-END: Internal error (serial.serialutil.SerialTimeoutException: Write timeout).
See Thonny's backend.log for more info.
You may need to press "Stop/Restart" or hard-reset your MicroPython device and try again.

Has Anybody succeeded in getting the MicroPython to function on the Wt9932P4 chips / Tiny boards ?

Hello
which is causing the I2C errors and crashes you are experiencing. For stable development,
we recommend using ESP-IDF or Arduino (C/C++). Regarding the reset button, please try holding the BOOT button while pressing RESET to enter download mode. You can find more information and resources on the official wiki: https://www.waveshare.com/wiki/ESP32-P4-NANO
Best regards,

Using the Esp32-P4-PICO dev board.
I can Not load microPython on it using Thonny.
Used bins :
ESP32_GENERIC_P4-20251209-v1.27.0.bin
ESP32_GENERIC_P4-20260406-v1.28.0.bin
Also, on initial plugin, it spit out a long list of I2C errors,
then Stack Dump Crashed.
Also, Reset buton does Not seem, to have any effect / does not reset the board.

> "Currently, MicroPython support for the ESP32-P4 series is still in a preliminary testing phase and has not been fully adapted,"
- Why is it out for SALES then ... ???
I have been trying to install MicroPython on the :
Waveshare Esp32-P4-Pico Dev Board
-- but all I get on restart after is an Invalid Header 0x4ff34537 error repeatedly - which then always locks-up Thonny
-- tried address 0x1000 - no difference
-- can not install it using CircuitPython - because there is No Generic_Esp32P4 bin there to use.
-- The chip also does not provide any popup Install Drive on the file browser.
It seems that you can Not use the SD Card - on the Esp32-P4 / Elecrow CrowPanel 10.1inch Advanced Display.
I (and many other across the Internet) can Not get the SD Card to work on the Esp32-P4.
- I am using the Elecron crowPaney 10inch ,
-- but it seems to being the behavior of the Esp32-P4 in genral
Also, Elecrow Customer / Gitub pages do not seem to respond to the requests for this Problem.
It seems to be across the forums.
Nobody can get SDCard to Read/Write on the Esp32-P4 in MicroPython or even C++.
The error code is 16 - 'Card already in use error'
CYD Esp-S3 boards - I have no problem.
- But , these Esp32-P4 / Elecrow CrowPanel 10.1inch Advanced Display - are a nightmare,
-- only a few MicroPython examples provided : LVGL & I2C read temp, thats it.
- Anybody see a solution to this problem ?
-> SOLVED : - see below
I constructed my own Assorted (3D Print) Boxes - for the CYD Cheap yellow display.
I will posts Prints / STLs for them when I get them up on Thingiverse.
Multiple versions :
* Simple small Box - with room for Batteries and Voltage Converter Boards.
* Larger Box - room for TT-Motors -or- Mounts for Sg90 Motors (for Spider Bot - and 18650 .Battery.
-- Will leave Updates as completed
Those return Labels that Ebay give you to Print,
are Not from Ebay,
they are provided by the Seller.
Apparently some ebay Sellers may provide you an INVALID / FAKE Return Tracking #.
So, they can claim that the Return Package was Not Shipped / Received.
So, the Seller does not need to refund the Order.
-
I had to return a Not Working Product.
But, apparently, the Seller provided a FAKE / INVALID Tracking # to Ebay for me to use for Returning the product.
I Photographed the Package, then personally gave the Package to the Postman.
But, few days later now, Usps still does Not record the Tracking# as Shipped.
I went to my post office, and the USPS office just states that it is a not Paid Tracking # / Invalid Tracking # / Not in the USPS system.
So, the package will be delivered to the seller, but I will Not get any Credit for the Return.
-
WHY :
Both Ebay and USPS state that the Return Label provided by ebay - used an INVALID / Fake Tracking #.
Ebay states that the SELLER provides the Return Label with Tracking # to ebay - which ebay does not verify if its valid.
So, this means that Sellers can and are starting to give Fake Return Labels to ebay for the buyer returns,
- and ebay does Not notice this problem.
