#104: flashrom: Change flash drivers to never erase data before writing ---------------------------------+------------------------------------------ Reporter: stuge | Owner: somebody Type: defect | Status: new Priority: major | Milestone: flashrom v1.0 Component: flashrom | Version: Keywords: erase write | Dependencies: #103 Patchstatus: there is no patch | ---------------------------------+------------------------------------------ The user should be responsible for ensuring that the flash chip has been erased where new data should be written. At the moment, flashrom will erase at least one full page and then rewrite it, when the user asks to only write a few bytes using -l/-i/-s/-e. -- Ticket URL: <http://tracker.coreboot.org/trac/coreboot/ticket/104> coreboot <http://www.coreboot.org/>

flashrom on MCP73

Hi guys, We are trying to make flashrom work on http://www.ecs.com.tw/ECSWebSite/Products/ProductsDetail.aspx?detailid=858&… Chipset MCP73 / SIP chipset Macronix MX25L8005. We made modifications using a enable_flash_mcp55 function, but does't work. ./flashrom -V -c MX25L8005 -r -f rom Calibrating delay loop... 627M loops per second, 100 myus = 199 us. OK. No coreboot table found. Found chipset "NVIDIA MCP73", enabling flash write... OK. Probing for Macronix MX25L8005, 1024 KB: spi_command called, but no SPI chipset/strapping detected No EEPROM/flash device found. Force read (-f -r -c) requested, forcing chip probe success: Probing for Macronix MX25L8005, 1024 KB: Found chip "Macronix MX25L8005" (1024 KB) at physical address 0xfff00000. Force reading flash... spi_chip_read called, but no SPI chipset/strapping detected 0 done. How can I do works? Are there any hints? Thanks! -- Fabrício Ceolin

Hi guys I don't know how usefull is it but there is a bug in cache_as_ram.inc and cache_as_ram_post.c for the 6fx intel processors. The code disable / enable the prefetcher in IA32_MISC_ENABLES MSR register. cache_as_ram.inc : /* Disable prefetchers */ movl $0x01a0, %eax rdmsr orl $((1 << 9) | (1 << 19)), %eax orl $((1 << 5) | (1 << 7)), %edx wrmsr should be movl $0x01a0, %ecx Same thing in cache_as_ram_post.c /* Enable prefetchers */ "movl $0x01a0, %eax\n" "rdmsr\n" "andl $~((1 << 9) | (1 << 19)), %eax\n" "andl $~((1 << 5) | (1 << 7)), %edx\n" "wrmsr\n" should be "movl $0x01a0, %ecx\n" Regards, Thomas
