Hello Flashrom, I'm on latest Linux Mint. programmer ch341a_spi chip is a Macronix type MX25L6406E I'm trying to erase a chip with: sudo flashrom --programmer ch341a_spi --erase -c "MX25L6406E/MX25L6408E" And I'm getting a erase failed. See log. pascal@pascal-mini:~/Desktop/Flashrom$ sudo flashrom --programmer ch341a_spi --erase -c "MX25L6406E/MX25L6408E" flashrom v1.2 on Linux 5.4.0-107-generic (x86_64) flashrom is free software, get the source code at https://flashrom.org Using clock_gettime for delay loops (clk_id: 1, resolution: 1ns). Found Macronix flash chip "MX25L6406E/MX25L6408E" (8192 kB, SPI) on ch341a_spi. Erasing and writing flash chip... FAILED at 0x00000000!

Looking for another erase function. No usable erase functions left. FAILED! Your flash chip is in an unknown state. Please report this on IRC at chat.freenode.net (channel #flashrom) or mail flashrom(a)flashrom.org, thanks! Any idea? Thanks Pascal

Questions regarding Easy projects
by Prakhar Agrawal 04 Apr '22

04 Apr '22

Hello, Hope you are doing well, I am Prakhar Agrawal, currently pursuing Electronics and Communications Engineering from Amrita Vishwa Vidhyapeetham Amritapuri. (2019-2022). For the past 1 year, I have been working with startups to design and develop low latency embedded devices and have also been actively involved in running and managing the bi0s students club(India's best CTF team) While going through different organizations for GSOC 2022, I found Flashrom, and it caught my interest. I was trying to get familiar with the flashrom code-base through easy projects listed here <https://www.flashrom.org/Easy_projects#Fix_issues_found_by_scan-build> I had a few queries in '*Fix issues found by scan-build':-* - In serprog.c, function static int sp_stream_buffer_op( ), if (!sp) { msg_perr("Error: cannot malloc command buffer\n"); return 1; } sp is a pointer, in which a block of memory is being allocated, but in this function, if (!sp) i.e pointer is not null, i.e the memory has been allocated, then why should there be an error message? - While fixing the error generated from the error report, null was being passed to memcpy, here if (sp_stream_buffer_op(S_CMD_O_EXEC, 0, NULL) != 0) to try and fix this issue, I updated the function definition static int sp_stream_buffer_op(uint8_t cmd, uint32_t parmlen, uint8_t *parms){ uint8_t *sp; if (sp_automatic_cmdcheck(cmd)) return 1; sp = malloc(1 + parmlen); if (!sp) { msg_perr("Error: cannot malloc command buffer\n"); return 1; } sp[0] = cmd; /* * Fixed: Added an If block to check the parameter length, * if parameter length is 0 i.e- param is NULL return 1, * else do memcpy */ if(parmlen==0){ //memcpy(&(sp[1]),0, parmlen); msg_perr("Error: Cannot pass Empty parameter\n"); return 1; } else{ memcpy(&(sp[1]),parms, parmlen); } The above changes fixed the error of null value being passed, but now I am getting a memory leak error. Can someone guide me in the right direction on how to fix it? Hoping for a quick and positive response. Warm Regards Prakhar Agrawal Amritapuri <https://www.amrita.edu/campus/amritapuri> LinkedIn <https://www.linkedin.com/in/prakar-agrawal-984555154/>
