--- ** [tickets:#350] stm32f07/9x wrong flash sector size ** **Status:** new **Milestone:** 0.11.0 **Created:** Thu May 05, 2022 02:11 PM UTC by Jan Hildenbrand **Last Updated:** Thu May 05, 2022 02:11 PM UTC **Owner:** nobody While trying to enable and disable write protect the problem arises that on a stm32f071 only the first 16 sectors can be enabled/disabled the latter 16 sectors cannot be changed. Furthermore, "flash info 0" shows a sector size of 8KB (which is wrong, it should be 4KB according to the stm32f0x reference manual - see https://www.st.com/resource/en/reference_manual/dm00031936-stm32f0x1stm32f0x2stm32f0x8-advanced-armbased-32bit-mcus-stmicroelectronics.pdf page 54) The root cause is the wrongly configured ppage_size (1 sector is 2 pages for stmf07/9x) The following patch solves the issue for me, but I only have stm32f072 to test. @@ -863,7 +863,7 @@ static int stm32x_probe(struct flash_bank *bank) break; case 0x448: /* stm32f07x */ page_size = 2048; - stm32x_info->ppage_size = 4; + stm32x_info->ppage_size = 2; max_flash_size_in_kb = 128; stm32x_info->user_data_offset = 16; stm32x_info->option_offset = 6; @@ -872,7 +872,7 @@ static int stm32x_probe(struct flash_bank *bank) break; case 0x442: /* stm32f09x */ page_size = 2048; - stm32x_info->ppage_size = 4; + stm32x_info->ppage_size = 2; max_flash_size_in_kb = 256; stm32x_info->user_data_offset = 16; stm32x_info->option_offset = 6; --- 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.
