Hi, I am unable to access mini2440 board neither in NOR nor in NAND type? Please help what to do? In that board I was using pengutronics Bsp with linux 3.1, it was working well yesterday, today when i tried to access it was refuse to boot in nand mode, after that I switch it to NOR, but it isn't booting in NOR also. Please let me know the possible steps to take. Thank you for your time in advance. regards, miniarm
Hmmm, The Pengutronix's BSP does not touch the NOR, to keep it as a last resort. Maybe something different died? (power supply?)
any possible workaround to bring it up back. Please let me know.
In the NAND position connect a serial cable and show us the boot log using minicom or something similar.
Is your power supply still at 5 V when you switch on your Mini2440? If also the NOR content is erased the only thing which comes into my mind is JTAG to get new software into the system.
@davef, I am not able to access board neither in NOR nor in NAND. @Juergen, Can i use the same JTAG Cable to load new software in board. I have never played with JTAG before, Can you please send me a good link/article of how to use JTAG cable with mini2440?
Search for <JTAGingtheNOR.pdf>
@davef, I have done the exact steps as per describe in pdf, but no luck. I have also tried Gautam instruction, but no luck. I tried searching for NOR flash type, but unable to find it on my board. on website I found STS and also choose same in procedure, but no luck. Please let me know the exact steps to take NORing new mini2440. Look forward to hear from you soon.
@miniarm, 1. Ensure your switch is in NOR position. Start the DNW utility (115200, 8, n, 1) and boot the board. Check for bootloader menu (Supervivi / UBoot). If not present, then bootloader needs to be flashed. (Follow steps given below) 2. Check FriendlyARM web site (downloads section) for Mini2440 manual and locate NOR chip position on circuit board. 3. Identify exact part number on chip package. 4. Start H-Jtag program. In that start, H-Flasher utility and load .hfc/.his file for your part from the DVD-ROM accompanying the board. 5. Press 'Check' button on H-Flasher dialog box. If part no. selection is incorrect, it will flash error, otherwise it will show Flash part ID. Till step 5 is reached, nothing else will work. Regards, Gautam Ghate
@Gautam, Please check the attached image. I am operating the board in NOR. It is successfully detected by Jtag software, but the problem is I am unable to find the Part number on the website. According to you I have explored the download section of mini2440 and I found this, but I am not able to get which FLASH I have to choose in H-Flasher utility. How can I find which NOR flash my board has? Flash K9F1208 64 MB NAND Flash K9F1G08 128 MB NAND Flash K9F2G08 256 MB NAND Flash K9K8G08 1024 MB NAND Flash AM29LV160D 2 MB NOR Flash SST39VF1601 2 MB NOR Flash And the same .his/hfc file will work that ship with the board itself? Please help me out there to identify the FLASH chip. Thank you for your time in advance. -- miniarm.
sorry, forgot to attach file.
@Gautam, Also please find the .his/hfc file available in my DVD, which file I have to choose?
Also how to find which NOR flash chip board contains? My problem look likes , it is not able to identify the proper NOR flash chip. Please let me know.
Hi Gautam, How to find the NOR flash device? Please Help, I have two board in dead condition. I want to recover it back.
Hi miniarm, If you have the 3.5" LCD board, use the attached picture to locate the NOR flash. Gautam
@Gautam, I am using 7" LCD and as per your instruction in NOR chip finding I found it has 'Spansion NOR flash chip on your board' but I am not able to find it in H-JTAG software. http://www.friendlyarm.net/forum/topic/3682 After installing version 1.0 and .hfc file from the link, it is still not working. In Programming section It give me 'can't halt target and make it enter debug state' Please Help. Let me know the steps for the Spansion NOR chip. Do I need to add delay command in script? Thank You for your time.
