+== Boot1 page size ==
+
+I'd noticed you've reverted edits where people have corrected boot1's page size. Boot0 only reads pages 0x0 through 0x2d, which is 47 total pages. I've verified this not only by looking at the code (see 0x0290) but also creating an emulator of the Starlet and monitoring NAND reads. Attempting to SHA-1 over the first 48 (rather than 47) pages of NAND also gives an incorrect boot1 hash.

+ if (stage < 0x2f) {
+ do {
+ /* wait for the NAND engine to be available */
+ } while (_NAND_CTRL < 0);
+ _NAND_DATABUF = &sram_start + stage * 0x800;
+ _NAND_ECCBUF = &sram_ecc_start + (stage & 1) * 0x80;
+ _NAND_CTRL = -0b01111111110011110100011111000000;
+ _NAND_ADDR2 = stage;
+ }
