of ATMEL, the chip integrates the Atmel initialization program at91rm9200, so you can skip the uboot initialization program for the CPU underlying layer, however, on our h9200m Development Board, the ultimate goal of ATMEL's initialization program is to use the XMODEM protocol to download the program into the CPU chip RAM, and the on-chip RAM only has 16 K of the Zone, it cannot accommodate our uboot. bin,

(3) The host controller at the host controller layer depends on different platforms. For example, the host controller at the S3C2410 card must be different from that at the Atmel card. Therefore, it must be implemented for different controllers. For example, if you want t

To display the logo, of course, the first thing we need to do is to modify and improve the LCD driver. I will not go into details about the driver modification. I will search for it online, but I recommend it.Tekkaman ninjaIt is certainly okay to refer to his blog.

The Atmel-based 8-bit low-power CMOS Proteus microcontroller, developed by ATMEL, features 1 MIPS/MHz performance, 16 K flash, 512-byte EEPROM, and 1 K-byte memory, 35 General I/O Ports, 32 general-purpose registers, three timers, internal and external interrupt sources, two programmable UART ports, SPI ports, and three power-saving modes that can be selected
SPI busThe serial peripheral interface bus is a three-line serial bus developed by Motorola for data transmission using three lines, which are the sck clock pins, SI data input pin and so data output pin. In addition, the CS chip selection pin can be used to select chips on the same bus, SPI bus has been widely used in EEPROM, single chip microcomputer and various devices. The 25xx series chips in commonly used serial EEPROM use the SPI-compatible bus structure and adopt the advanced coms techno

If you want to further crack the firmware, you can use vbindiff to compare the two different firmware versions:
Note:Files are different in 16-byte blocks. Some blocks are intertwined with other blocks.
This indicates that this is probably a group password in ECB mode. The most common 16-byte password is A
, plus the Contiki core and C libraries, and the complete system image is close to 30KB. Using manual wired reprogramming, programming for a separate sensor node took more than 30 seconds. With a total of 40 checkpoints, it takes at least 30 minutes to program the entire network. Conversely, by means of the aerial reprogramming method, only 2 minutes were used, which reduced an order of magnitude.9.2 Code SizeTable 1.

It is worth mentioning that some JTAG accessors have jumpers on the schematic to enable the reset signal, which generally does not jump on. That is, no reset signal is required, because 44b0 reset can also be controlled in the JTAG protocol.
Of course, the reset signal jumper on the Board does not need to jump.
