This article will break down why this happens and how to fix it. What Does "Contents are in Disagreement" Mean? The CH341A software operates in three steps: . Erase: Sets all bits to (or FF in hex). Write: Sets specific bits to as required by the firmware file.
SPI Flash chips have a Status Register. If the bits are set, the chip will ignore write commands. The software will say "Write Complete," but when it verifies, it reads the old data, causing a disagreement.
When combined with the CH341A’s fast default clock speed, these chips return garbage data during verification. This article will break down why this happens
If you see the "Contents are in disagreement" message, try these steps in order: or check your solder joints. Clean the chip pins. Use NeoProgrammer instead of the stock software.
"Chip main memory with the contents are in disagreement" typically occurs when the CH341A programmer's software fails to verify that the data written to the chip matches the source file byte-for-byte. This verification failure is often caused by hardware connectivity issues, voltage mismatches, or software bugs. Win-Raid Forum Common Fixes for "Contents are in Disagreement" Erase: Sets all bits to (or FF in hex)
Many inexpensive "black" CH341A programmers do not perform proper level shifting. Applying 5V to the input pins of a 3.3V or 1.8V chip can cause erratic behavior and, in the worst case, permanent damage.
Which are you currently running? Share public link If the bits are set, the chip will ignore write commands
A poor connection on Pin 4 (GND) or Pin 8 (VCC) will let the chip respond to initial identification commands but drop out under the heavy power draw required during write operations. 2. Motherboard Circuit Interference (In-Circuit Flashing)
