Release Notes

1.14

• Fixed bitfield descriptions of PWM interrupt registers in memory maps and header files.
• Fixed SRAM size of AT91SAM7S512 memory map file.
• Added EABI and small library variants of libat91sam7 library.

1.13

• Added support for AT91SAM7S16 and AT91SAM7S161.
• Updated definition of ADC_MR register to reflect changes in documentation.

1.12

• Now works with CrossWorks V2.x with restricted memory accesses enabled.

1.11

• Corrected internal FLASH LIBMEM driver's AT91SAM7L64 FLASH geometry.
• Internal FLASH LIBMEM driver can now write to a page after failure to write to a different page.
• Accelerate the internal FLASH LIBMEM driver's lock and unlock functions.

1.10

• Fixed AT91SAM7.h so that it correctly includes the AT91SAM7X512 and AT91SAM7XC512 header files.

1.9

• Improved the remapping of RAM to 0x00000000 in the startup code and reset script so that it copes with the case where RAM is already mapped to 0x00000000.

1.8

• Added support for AT91SAM7L64 and AT91SAM7L128.
• Loaders now set the boot from internal FLASH NVM bit by default.

1.7

• ctl_at91sam7_get_mck_frequency now returns correct value when Main Clock is selected.

1.6

• AT91SAM7 LIBMEM driver now resets watchdog while busy waiting.

1.5

• AT91SAMX512 and AT91SAMXC512 memory map and header files now specify EFC1.
• Reset script now works with AT91SAM7X512

1.4

• Reset scripts can now use 1.7's TargetScript.setMaximumJTAGFrequency() function in order to improve download performance and reliability.

1.3

• Added .libat91sam7 suffix to all libat91sam7 program sections.
• Added libat91sam7_get_ram_size function.
• Added RPC loader in order to improve FLASH programming performance when using FT2232 based JTAG interfaces and J-Link.
• Fixed external executable project template.
• Startup code now programs up UDPCK.
• Added support for AT91SAM7SE devices.
• PIT is now used for ctl timer.
• AIC protected mode now enabled by default.
• The ctl interrupt handler now checks for spurious interrupts.

1.2

• The libat91sam7 LIBMEM flash driver erase function now correctly returns LIBMEM_STATUS_LOCKED when attempting to erase locked FLASH.

1.1

• Modified loader memory map so that .libmem sections will be placed correctly.
• Fixed startup code so that it is compatible with the new assembler in 1.6 build 3.

1.0

• Initial Release.
