Hello I have made same minor changes to make a better support for flashing a pic32mx220f032b chip. This chip has 3k boot flash, 32k program flash an 8k ram. Page size is 1k bytes or 256 words. Row size is 128 bytes or 32 words.
The modifications were made in src/flash/nor/pic32mx.c The output of diff: 53,56c53,56 < #define PIC32MX_DEVCFG0 0xBFC02FFC < #define PIC32MX_DEVCFG1 0xBFC02FF8 < #define PIC32MX_DEVCFG2 0xBFC02FF4 < #define PIC32MX_DEVCFG3 0xBFC02FF0 --- > #define PIC32MX_DEVCFG0 0xBFC00BFC > #define PIC32MX_DEVCFG1 0xBFC00BF8 > #define PIC32MX_DEVCFG2 0xBFC00BF4 > #define PIC32MX_DEVCFG3 0xBFC00BF0 340c340 < 0x2CD30080, /* sltiu $s3, $a2, 128 */ --- > 0x2CD30020, /* sltiu $s3, $a2, 128----->32 */ 346,347c346,347 < 0x24840200, /* addiu $a0, $a0, 512 */ < 0x24A50200, /* addiu $a1, $a1, 512 */ --- > 0x24840080, /* addiu $a0, $a0, 512 ----->128 */ > 0x24A50080, /* addiu $a1, $a1, 512 ----->128*/ 349c349 < 0x24C6FF80, /* addiu $a2, $a2, -128 */ --- > 0x24C6FFE0, /* addiu $a2, $a2, -128 ------> -32*/ 633c633 < page_size = 4096; --- > page_size = 1024; 648c648 < num_pages = (12 * 1024); --- > num_pages = (3 * 1024); 656c656 < num_pages = (512 * 1024); --- > num_pages = (32 * 1024); In this chip resolution of the BMX registers (Program/Data RAM) is 1k not 2K. Now programming flash and erasing sectors work ok. Hope someone is interested in adding support for this kind of chips. Thanks for your good good work.
