/* The GD32F450ZKT6 has 3072Kb of FLASH beginning at address 0x0800:0000 and
|
|
* 256Kb of SRAM. SRAM is split up into four blocks:
|
|
*
|
|
* 1) 112Kb of SRAM beginning at address 0x2000:0000
|
|
* 2) 16Kb of SRAM beginning at address 0x2001:c000
|
|
* 3) 64Kb of SRAM beginning at address 0x2002:0000
|
|
* 4) 64Kb of TCMSRAM beginning at address 0x1000:0000
|
|
*
|
|
* When booting from FLASH, FLASH memory is aliased to address 0x0000:0000
|
|
* where the code expects to begin execution by jumping to the entry point in
|
|
* the 0x0800:0000 address
|
