Well, as the initial version (simple SPI) was largely copy-and-paste from my stmqspi driver, two weekends as far as I remember (the most cumbersome parts were I2C and UNI/O interface). BUT: All required infrastructure in OpenOCD for Cortex-M was already there. Can't say anything about Cortex-A in this respect.
--- **[tickets:#400] Xilinx Zynq: Read/Write external QSPI Flash** **Status:** new **Milestone:** 0.10.0 **Created:** Mon Jun 05, 2023 06:20 PM UTC by Dominik Wernberger **Last Updated:** Mon Jun 05, 2023 07:45 PM UTC **Owner:** nobody Hi everyone, I have a system with a Xilinx Zynq (xc7z020) that has an external QSPI NOR Flash. Do you know if it's already possible to read write the Flash module? I have already googled a lot but haven't found any hints how to achieve this. The code base does not seem to provide this feature, although I'm not too familiar with it. If it is not implemented yet, could you guide me what exactly needs to be done to get this working? Fortunately the Flash chip is already present in `src/flash/nor/spi.c` BR Dom --- Sent from sourceforge.net because openocd-devel@lists.sourceforge.net is subscribed to https://sourceforge.net/p/openocd/tickets/ To unsubscribe from further messages, a project admin can change settings at https://sourceforge.net/p/openocd/admin/tickets/options.
