Structure containing parameters for boot0:
Structure containing parameters for boot0:
− - 0x1C0 to 0x1C2 (0x02 bytes): Control flags.
+ - 0x1C0 to 0x1C2 (0x02 bytes): Control flags (clock config?):
− - 0x1C2 to 0x1C4 (0x02 bytes): Control flags:
+ -> bits 0-9 set the cpu speed in MHz used for various IO delay calculations.
− -> 0x4000 tells boot0 to overwrite NAND_CONFIG with the supplied value.
+ -> bit 15, if set, causes 0x3 to be written to LT_IOP2X and waits for interrupt (presumably after clock increased)
− -> 0x2000 tells boot0 to overwrite NAND_BANK with the supplied value.
+ - 0x1C2 to 0x1C4 (0x02 bytes): Control flags (NAND config):
+ -> bit 13 tells boot0 to overwrite NAND_BANK with the supplied value.
+ -> bit 14 tells boot0 to overwrite NAND_CONFIG with the supplied value.
- 0x1C4 to 0x1C8 (0x04 bytes): Value to overwrite NAND_CONFIG (optional).
- 0x1C4 to 0x1C8 (0x04 bytes): Value to overwrite NAND_CONFIG (optional).
- 0x1C8 to 0x1CC (0x04 bytes): Value to overwrite NAND_BANK (optional).
- 0x1C8 to 0x1CC (0x04 bytes): Value to overwrite NAND_BANK (optional).
