[embedded]

I want to generate a .bin file using the code in B4J and also want to read this file because data organize in bin file is in matrix form. i want to save a series of data in the flash memory of ESP32 because it has limited memory. Any help appriciated.

I don't like to see questions go unanswered, but I have removed my first response because I think that I misunderstood the question.

I think that you are asking about DMA on an ESP32. Not my area really, but I think that it would be unlikely - a bit like reading a handful of bytes from the middle of a serial file. There seems to be a similar question here, but the answer there is also unclear.
