Request support for xmc qh64ahig, qh128ahig
by M. Jacobs 11 Oct '24

Dear sir/madam, After reading the changelog for version 1.3 I saw that the XM25QH64C and XM25QH128C are supported. However I am trying to use flashrom with a ch341 (pro) to read and write qh64ahig/qh128ahig eeproms. It fails saying no eeprom/flash device found which comes down to lack of support I guess. Are there any plans in the nearby feature for implementing these models of IC's? Kind regards, MJ

Need help - Segmentation fault 11 when trying to write
by Flaviu Ciobanu 01 Oct '24

Hi devs! I previously successfully used flashrom to read and patch a MX25L6406E BIOS chip in a late 2013 15" MacBook Pro with a Ch341a programmer, but I am now having issues trying to write to a 25Q064A BIOS chip in a mid 2014 15" MacBook Pro. I installed flashrom with homebrew. I connected the SOP8 clip to the chip, then the adapter, then the CH341A. I read the chip into an image.bin file 3 times and compared MD5 sums to make sure they were the same. I then patched the file with UEFI Patch to unlock undervolting ( https://github.com/IsmaelHG/UndervoltPatchMacBook). I then ran the write command in terminal. You can see the command and the output pasted below ending in "Segmentation fault: 11". Should I try erasing the chip first? I'm scared I will brick it if it still can't write afterward. What else can I try? Terminal output: sudo flashrom -V -p ch341a_spi -c N25Q064..3E -w /Users/Flyview/Downloads/UEFIPatch_0.28.0_mac/image.bin flashrom 1.4.0 on Darwin 23.6.0 (x86_64) flashrom is free software, get the source code at https://flashrom.org flashrom was built with LLVM Clang 15.0.0 (clang-1500.3.9.4), little endian Command line (7 args): flashrom -V -p ch341a_spi -c N25Q064..3E -w /Users/Flyview/Downloads/UEFIPatch_0.28.0_mac/image.bin Initializing ch341a_spi programmer libusb: info [darwin_detach_kernel_driver] no capture entitlements. may not be able to detach the kernel driver for this device Device revision is 3.0.4 The following protocols are supported: SPI.

This flash part has status UNTESTED for operations: WP The test status of this chip may have been updated in the latest development version of flashrom. If you are running the latest development version, please email a report to flashrom(a)flashrom.org if any of the above operations work correctly for you with this flash chip. Please include the flashrom log file for all operations you tested (see the man page for details), and mention which mainboard or programmer you tested in the subject line.
