ADS1102CAL dead on firmware upgrade progress (((
(1/1)
SergeyOSV:
Hello everyone! my problem - my ADS1102 CAL died on firmware software ((in the firmware are removed. Now I have to repair it.
what I did:
read many topics on the forums, and came to the conclusion that ADS1102CAL and SDS1102CNL on the same hardware.
found a software update for SDS1102CNL.
dismantled its ADS1102CAL, made sure that he twin SDS1102CNL, took the chip FLASH and read it on the programmer.
compared bin-file from FLASH and software updates for SDS1102CNL and found out that the update has reversed bytes, converted it to a normal view.
further found that the code in the FLASH obnovleniyalozhitsya offset 0h001E0000.
At each stage of work with firmware, making the steps I sews FLASH, installed it and tested it in ADS1102CAL. It is not possible to repair my ADS1102CAL ((((
now the heart of the matter:
maybe someone wants to help me and will be able to. I need a bin-file from your ADS1102CAL
can someone be able to read the chip FLASH programmer working with the oscilloscope and send it to me - my gratitude would be high!
Thank you!
what do you say?

If the machines are the same then byte order cannot be reversed. I think you messed up the flash contents big time....

You misunderstood me!
FLASH file in the normal way, I have not changed!
Package files to update software includes bin firmware BUT INVERTED! Beginning of the file is the end of the firmware file and the end - the beginning of the firmware!
I changed back to the late ONLY upgrade file, compare the results obtained with the FLASH memory. matched.
But! Now I need to know in what part of the FLASH CONFIG file to be written, and it is impossible to calculate - before writing the software update, the processor has erased some of FLASH (preparation for writing updates) (((
I need a sample code that is working ADS1102CAL
then I can understand the structure of FLASH, I can fix your oscilloscope!

What did you ever do regarding this problem ?
Tryel:
Here - https://youtu.be/EFNX3YjZdV4 shows how to make a memory dump and the author of the video made a dump of the firmware before installing the long memory chip and after the memory increase. He has the dumps.
