[AMD Official Use Only - AMD Internal Distribution Only] Hi,
Thanks for all your help. I have an update. We came up with a 16MB ROM file booting with AMD-BirmanPlus board with 64MB flash chip size. I would like to know if there is any way to flash 16MB ROM file to the GD25LR512ME flash chip using the internal programmer. Thanks in advance! Regards, Avinash. ________________________________ From: Anastasia Klimchuk <a...@chromium.org> Sent: Tuesday, May 14, 2024 5:05 PM To: Vlim <v...@gigadevice.com>; Munduru, Avinash <avinash.mund...@amd.com>; flashrom@flashrom.org <flashrom@flashrom.org> Subject: Re: [flashrom] Re: Support for GD25LR512ME flash chip. Caution: This message originated from an External Source. Use proper caution when opening attachments, clicking links, or responding. Victor, Thank you so much for the datasheets! I did a review of the pending patch, and now it will be possible to finally finish the patch from 2021 and get the chips submitted. Also thank you for attaching the log. Not sure if the log is complete? It ends at the start of the reading operation, but there is no final message of SUCCESS or FAIL. However, importantly, I could see in the beginning of the log which platform was detected, and it is Promontory. Which means... Avinash, Most likely you are hitting a known issue, you can read more details here: https://ticket.coreboot.org/issues/370 The issue is for Promontory, and also for chips larger than 16Mbyte: which is exactly what you have. I was actually trying to get help from AMD with this issue, so it's really good to have you here on the mailing list! Maybe you can help? Someone from AMD would be in the best position to fix Promontory, you have all the datasheets available, and all the hardware. Thank you!
