Hello everybody, I would like to share some info about SAME70 work in progress and material to share.
Due to the chip crisis Elektroline has switched in a hurry to SAME7x by start of this year and we provide some consultations and help with NuttX in general and for this target as well. The most of the NuttX changes are available in their public repo https://gitlab.com/elektroline-predator/nuttx As for the SAME, there has been need to update CAN controller support, because revision B switched to newer version of BOSCH M-CAN IP core. There are some patches on the next and related branches https://gitlab.com/elektroline-predator/nuttx/-/commits/same70_revb Milos Pokorny from Elektroline updated CAN header files and driver https://gitlab.com/elektroline-predator/nuttx/-/commit/1306a0e739cc8a97e4b3c28e7fa35731343830e5 https://gitlab.com/elektroline-predator/nuttx/-/commit/5aec4cedb641ebe504dabf08e3bd48a83486454d it would be perfect to get this to mainline, but changes break compatability with A revision and we are not sure, if there are some project which require it. When I or somebody else finds time and we get some feedback what is preferred solution (dynamic switch according to the found M-CAN revision, Kconfig option...) then we try to push that into mainline. Jaroslav Beran from Elektroline bushed changes making character /dev/can interface usable for CAN FD into mainline already. There is header file for SAME70 AFE prepared by Milos Pokorny https://gitlab.com/elektroline-predator/nuttx/-/commit/3fa4e624a28c9a6836895119e7dd41afec7eae88 https://gitlab.com/elektroline-predator/nuttx/-/commit/617015e84910a95ed2faf9b198b34059e6a947d7 Due to the lack of time during raid switch to available chip and minimal requirement, the proper ADC driver has not been implemented. But I have that task on my queue from Elektroline and thanks to generic ADC enhancements from Michal Lenc GSoC, I think that it would be good match with prepared Elektroline application. If there is interrest I can try to ask colleagues and extract some working "user space" examles how to manipulate with AFE in the polling mode. I would be happy if I get information on SAME70 work and if we can coordinate effort to lower duplication and find as good as possible solutions. My another task is to implent bootloader which allows updates of the application remotely over CAN bus. I have provided that for STM32L476RE with sysless project based on CUBE which can load sysless and NuttX applications. In the case of SAME70, I would like to avoid to learn and fight with producer provided sysless support and use minimal NuttX as the bootloader to chain boot into full NuttX system with application which can be rebootted back into loader and allows remote updates. I expect that all my work will be public, but it is possible that some safety and specific board tweaks stay in private repo. Elektroline system HW design with another safety microcontroller, where SAME70 ad NuttX is only non-critical communication bridge for diagnostics and monitoring, applications for both etc... are not intended for public... But all my generic NuttX work is. Yours sincerely Pavel Pisa ================================================== PiKRON s.r.o.
