RT1176 Not able to program MT25QL256ABA8E12 flash Got "20107 (0x4e8b) FlexSPINOR: SFDP Not Found." error when trying to program a new 3.3V NOR flash, MT25QL256ABA8E12. Previously, we were able to successfully program the NOR Flash over USB in our last rev hardware. The key difference in EV design is the NOR Flash device: we have moved to the MT25QL256ABA8E12-0AAT, which is from the same flash series but is a 3.3V, automotive-grade part. Old flash: MT25QU256ABA8E12-1SIT New flash: MT25QL256ABA8E12-0AAT A steady 3.3V is supplied to NVCC_SD2 for this change and 3.3V rail is updated for the new 3.3V NOR Flash as well. Please take a look and let me know if there is any other settings I need to do for flashing. Re: RT1176 Not able to program MT25QL256ABA8E12 flash Hi Gavin, Thanks. Please find attached full Write with the complete FCB configuration in SEC log. Please take a look and let me know. One datapoint that I want to share is when I probed the NOR signals, I noticed that the RESET# net is pulled to 1.1-1.3V, which is not expected and I do not have a good explanation for this observation yet. Chris Re: RT1176 Not able to program MT25QL256ABA8E12 flash thanks. Confirmed that the design includes all the 3.3V rail updates. Re: RT1176 Not able to program MT25QL256ABA8E12 flash Beside SFDP, the supply voltage change may result in different schematics design since 1.8V need to change to 3.3V. Please modify the related NOR VCC schematics and PCB layout from 1.8V to 3.3V as well Re: RT1176 Not able to program MT25QL256ABA8E12 flash Hi @chryao ,
Thanks for your reaching out!
The "complete FCB" test only initializes the FlexSPI controller using the parameters inside the FCB. No erase, program, or read was performed on the flash, so it does not confirm that the flash is actually responding. In contrast, the simplified option (0xC0000005) requires reading the SFDP table from the flash, and this was the only real flash access in both logs. It failed with 20107.
Could you please run a full Write with the complete FCB configuration in SEC without XMCD and share the complete log? Additionally, it is advisable to first perform a test in normal boot mode where the RAM code accesses (reads/writes) the Flash memory, in order to rule out any potential hardware-related issues.
Best regards, Gavin
