Трансиверы, приемники КВ/УКВ / Re: Baofeng DM-32
« Последний ответ от igor 02 Мая 2026, 10:01:11 »I figured out how firmware protection is implemented in the Baofeng DM-32. The ALPU-MP chip, connected to the processor's I2C bus, protects the firmware from unauthorized copying and use. The private key is stored in flash memory; if the flash memory is damaged or a memory image from another radio is used, the radio will not function correctly! The backup flash memory will only work with the radio from which the image was obtained! Currently, I cannot bypass this protection...как сделать копию флэш памяти и где она?
If anyone is planning to experiment with firmware, be sure to have a backup copy of your radio's flash memory!!!
In the attachment, exchange via the CPU<-> ALPU-MP and datasheet
