Dave,

I am about to try this.

Will update you once I'm done with this

Thanks again!!

Dave!! Thank you for the reply. I am getting this weird EINVAL22 at times while using SD Card in my custom hw(uses stm32 port). I have been basically trying to do a FOTA with the GSM module as described below 1. Download firmware0.bin to 0x08020000 and firmware1.bin to 0x08040000 in-house using STM3...

Hello Everyone!!


I'm so curious to know what the are source files that (when the contents changed) contributes to modification of firmware0.bin and what those does so to firmware1.bin.

FYI : I have been using STM32 port of micropython.

Thanks in advance!!

Thanks Dave for the quick reply!!

Let me look into it. But Dave, How do i get the info on file and line number ??

Hello Everyone!!

I have a question with respect to UART in pyb class.

Referring to the following picture, where from the buffer size is allocated for the parameter read_buf_len.

Is it from RAM?


I'm so sorry if my question doesn't make sense.

Hi Maksym!! Thought of giving it a try and finally got the output It is MemoryError: memory allocation failed, allocating 31655 bytes MicroPython 8dc4982-dirty on 2019-02-09; MySTM with STM32F405VG Type "help()" for more information. This happens at random time intervals after restart. What am I mis...

Hello Everyone!! I have done a custom bootloader for stm32f405vg using IAR workbench. Inside the bootloader, I do the following. 1. Mount a SD card 2. Check for a file named "KTT.bin" in that using fr = f_open(&SDFile, CONF_FILENAME, FA_READ); which returns FatFs Error 4 (FR_NO_FILE) in the absence ...

In order to execute a frozen main.py or boot.py then you need to modify main.c to do something like this: https://github.com/micropython/micropython/blob/67689bfd7e28df8d4fa23c8f25065aeb0b9d9658/ports/teensy/main.c#L315 The current main.c will only execute main.py from a filesystem, not as a frozen...

Dave I have a question here. This seem to run when I make reset_mode=1 manually as discussed in my above thread.


Is there any specific reason for this behavior?


Thanks again!!
